	Organization
	America First Multifamily Investors, L.P. (the “Partnership”) was formed on April 2, 1998, under the Delaware Revised Uniform Limited Partnership Act for the purpose of acquiring, holding, selling and otherwise dealing with a portfolio of mortgage revenue bonds which have been issued to provide construction and/or permanent financing of multifamily residential apartments. The Partnership expects and believes the interest earned on these bonds is excludable from gross income for federal income tax purposes.  As a result, most of the income earned by the Partnership is exempt from federal income taxes.  Our general partner is America First Capital Associates Limited Partnership Two (“AFCA 2” or “General Partner”).  The Partnership will terminate on December 31, 2050, unless terminated earlier under provisions of its Agreement of Limited Partnership.

	Summary of Significant Accounting Policies
	Principles of Consolidation
	The “Company” refers to the Partnership and the consolidated VIEs (defined below). The consolidated financial statements of the Company reported in this Form 10-K include the financial position and results of operations of the Partnership, the MF Properties owned by various limited partnerships in which one of the Partnership's wholly-owned subsidiaries (each a “Holding Company”) holds a 99% limited partner interest, two entities in which the Partnership does not hold an ownership interest but which own multifamily apartment properties financed with mortgage revenue bonds held by the Partnership and which are treated as variable interest entities ("VIEs") of which the Partnership has been determined to be the primary beneficiary (the “Consolidated VIEs”). The Consolidated Subsidiaries of the Partnership consist of:
	•	ATAX TEBS I, LLC, a special purpose entity owned and controlled by the Partnership, created to hold mortgage revenue bonds in order to facilitate the Tax Exempt Bond Securitization (“TEBS”) Financing with Freddie Mac (Note 10).
	•	Nine multifamily apartments ("MF Properties") which are either wholly or majority owned by subsidiaries of the Partnership.
	Under the consolidation guidance, the Partnership must make an evaluation of the entities which own the multifamily properties financed with mortgage revenue bonds it holds to determine if these entities meet the definition of a VIE. Generally, a VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support; (b) as a group, the holders of the equity investment at risk lack (i) the ability to make decisions about an entity's activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests and substantially all of the entity's activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights.
	The guidance requires the Partnership to perform an analysis to determine whether its variable interests give it a controlling financial interest in a VIE. This analysis identifies the primary beneficiary, the entity that must consolidate the VIE, as the entity that has (1) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.  Upon adoption of this revised accounting standard, the Partnership re-evaluated all of its investments to determine if the property owners are VIEs and, if so, whether the Partnership is the primary beneficiary of the VIE. The guidance also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. As a result, changes to the Consolidated VIEs may occur in the future based on changes in circumstances. The accounting guidance on consolidations is complex and requires significant analysis and judgment.
	Stand-alone financial information of the Partnership reported in this Form 10-K includes only the financial position and results of operation of the Partnership and the MF Properties without the consolidation of the VIEs.  In the Company's consolidated financial statements, all transactions and accounts between the Partnership, the MF Properties and the VIEs have been eliminated in consolidation.
	The General Partner does not believe that the consolidation of the VIEs for reporting under generally accepted accounting principles in the United States of America (“GAAP”) impacts the Partnership's tax status, amounts reported to Beneficial Unit Certificate (“BUC”) holders on IRS Form K-1, the Partnership's ability to distribute income to unitholders which it believes to be tax-exempt, the current level of quarterly distributions or the tax-exempt status of the underlying mortgage revenue bonds.
	Acquisition Accounting
	Pursuant to the guidance on acquisition accounting, the Company allocates the total acquisition cost of a property acquired to the land, building, and leases in existence as of the date of acquisition based on their relative fair values.  The building is valued as if vacant. The estimated valuation of in-place leases is calculated by applying a risk-adjusted discount rate to the projected cash flow deficit at each property during an assumed lease-up period for these properties. This allocated cost is amortized over the average remaining term of the leases and is included in the statement of operations under depreciation and amortization expense.
	Cash and Cash Equivalents
	Cash and cash equivalents include highly liquid securities and investments in federally tax-exempt securities with maturities of three months or less when purchased.
	Concentration of Credit Risk
	The Company maintains the majority of its unrestricted cash balances at two financial institutions.  The balances insured by the Federal Deposit Insurance Corporation is equal to $250,000 at each institution.  At various times the cash balances exceeded the $250,000 limit.  The Company is also exposed to risk on its short-term investments in the event of non-performance by counterparties.  The Company does not anticipate any non-performance.  This risk is minimized significantly by the Company's portfolio being restricted to investment grade securities.
	Restricted Cash
	Restricted cash, which is legally restricted to use, is comprised of resident security deposits, required maintenance reserves, escrowed funds, restricted compensating balances, and property rehabilitation.  At December 31, 2013, certain of our credit facilities require restricted cash balances as additional collateral. Specifically, the mortgage revenue bond securitization ("TEBS") financing facility, discussed below, required approximately $727,000, the three tender option bonds ("TOB") trusts ("TOB Trusts") secured by the Public Housing Capital Fund Trust Certificates ("PHC Certificates") financing facilities (“PHC TOB Trusts”) required approximately $400,000, and the TOB Trusts secured by mortgage backed securities ("MBS") financing facilities ("MBS TOB Trusts") required approximately $4.1 million held in restricted cash. There were two of the mortgage payables which required approximately $2.9 million held as restricted cash in 2012 which was released in 2013.
	Investment in Mortgage Revenue Bonds and Other Mortgage Revenue Bonds
	The Company accounts for its investments in mortgage revenue bonds and other mortgage revenue bonds under the guidance for accounting for certain investments in debt and equity securities. The guidance requires investments in securities to be classified as one of the following: 1) held-to-maturity, 2) available-for-sale, or 3) trading securities. All of the Company's investments in mortgage revenue bonds and other mortgage revenue bonds are classified as available-for-sale, and are reported at estimated fair value with the net unrealized gains or losses reflected in other comprehensive income. Unrealized gains and losses do not affect the cash flow of the bonds, distributions to unitholders, or the characterization of the interest income of the financial obligation of the underlying collateral.
	There is no active trading market for the bonds and price quotes for the bonds are not available.  As a result, the Company bases its estimate of fair value of the mortgage revenue bonds using discounted cash flow or yield to maturity analyses performed by management. This calculation methodology encompasses a significant amount of management judgment in its application.  If available, management may also consider price quotes on similar bonds or other information from external sources, such as pricing services or broker quotes.  Pricing services, broker quotes and management's analyses provide indicative pricing only.
	The Company periodically reviews each of its mortgage revenue bonds for impairment.  The Company evaluates whether unrealized losses are considered to be other-than-temporary based on a number of factors including:
	•	The duration and severity of the decline in fair value,
	•	The Company's intent to hold and the likelihood of it being required to sell the security before its value recovers,
	•	Adverse conditions specifically related to the security, its collateral, or both,
	•	Volatility of the fair value of the security,
	•	The likelihood of the borrower being able to make payments,
	•	Failure of the issuer to make scheduled interest or principal payments, and
	•	Recoveries or additional declines in fair value after the balance sheet date.
	While the Company evaluates all available information, it focuses specifically on whether it has the intent to sell the securities prior to the time that their value recovers or until maturity, whether it is likely that the Company will be required to sell the securities before a recovery in value and whether the Company expects to recover the securities' entire amortized cost basis.  The ability to recover the securities' entire amortized cost basis is based on the likelihood of the issuer being able to make required principal and interest payments on the security.  The primary source of repayment of the amortized cost is the cash flows produced by the property which serve as the collateral for the bonds.  The Company utilizes a discounted cash flow model for the underlying property that serves as collateral on the bond and compares the results of the model to the amortized cost basis of the bond.  These models reflect the cash flows expected to be generated by the underlying properties over a ten year period, including an assumed property sale at the end of year ten, discounted using the effective interest rate on the bonds in accordance with the accounting guidance on other-than-temporary impairment of debt securities.  The inputs to these models require management to make assumptions, the most significant of which include:
	•	Revenue and expense projections for the property operations, which result in the estimated net operating income generated over the ten year holding period assumed in the model.  Base year (model year one) assumptions are based on historical financial results and operating budget information.  Base year assumptions are then adjusted for expected changes in occupancy, rental rates and expenses, and
	•	The capitalization rate utilized to estimate the sales proceeds from an assumed property sale in year ten of the model.  The capitalization rate used in the current year models ranged between 6.25% and 7.25% which the Company believes represents a reasonable range given the current market for multifamily properties.
	The revenue, expense and resulting net operating income projections which are the basis for the discounted cash flow model are based on judgment.  Operating results from a multifamily residential property depend on the rental and occupancy rates of the property and the level of operating expenses.  Occupancy rates and rents are directly affected by the supply of and demand for apartments in the market areas in which a property is located.  This, in turn, is affected by several factors such as local or national economic conditions, the amount of new apartment construction and interest rates on single-family mortgage loans.  In addition, factors such as government regulation, inflation, real estate and other taxes, labor problems and natural disasters can affect the economic operations of a property.
	If the discounted cash flows from a property are less than the amortized cost of the bond, the Company believes that there is a strong indication that the cash flows from the property will not support the payment of the required principal and interest on the bond and, accordingly, the bonds are considered other-than-temporarily impaired.  If an other-than-temporary impairment exists, the amortized cost basis of the mortgage revenue bond is written down to its estimated fair value.  The amount of the write-down representing a credit loss is accounted for as a realized loss on the statement of operations.  The amount of the write-down representing a non-credit loss is recorded to other comprehensive income. The difference between the amortized cost basis and the discounted cash flows using the effective interest rate represents the credit loss. Any residual decline in value would be considered the interest related loss or non-credit loss. The recognition of an other-than-temporary impairment and the potential impairment analysis are subject to a considerable degree of judgment, the results of which when applied under different conditions or assumptions could have a material impact on the financial statements. If the Company experiences deterioration in the values of its investment portfolio, the Company may incur impairments to its investment portfolio which could negatively impact the Company's financial condition, cash flows, and reported earnings.
	The Company owns some mortgage revenue bonds which were purchased at a discount or premium. The discount or premium on an investment is amortized on an effective yield method and the result is realized in investment income in the current period.
	The Company eliminates the mortgage revenue bonds and the associated interest income and interest receivable when it consolidates the underlying real estate collateral in accordance with implementation of the consolidation guidance for variable interest entities.
	Variable Interest Entities (“VIEs”)
	When the Partnership invests in a mortgage revenue bond which is collateralized by a multifamily property, the Partnership will evaluate the entity which owns the property financed by the mortgage revenue bond to determine if it is a VIE as defined by the guidance on consolidations. The guidance on consolidations is a complex standard that requires significant analysis and judgment. If it is determined that the entity is a VIE, the Partnership will then evaluate if it is the primary beneficiary of such VIE, by determining whether the Partnership will absorb the majority of the VIE's expected losses, receive a majority of the VIE's residual returns, or both. If the Partnership determines itself to be the primary beneficiary of the VIE, then the assets, liabilities and financial results of the related multifamily property will be consolidated in the Partnership's financial statements. As a result of such consolidation, the debt financing provided by the Partnership to such consolidated VIE will be eliminated as part of the consolidation process. However, the Partnership will continue to receive interest and principal payments on such debt and these payments will retain their characterization as either mortgage revenue bond or taxable interest for income tax reporting purposes. Since the Partnership has no legal ownership of the VIEs, creditors of the VIEs have no recourse to the Partnership.
	Effective December 1, 2013, the ownership of Lake Forest became a not-for-profit entity, a reconsideration event. As a result of the change in ownership, Lake Forest ceased to be reported as a Consolidated VIE.
	Investment in Public Housing Capital Fund Trusts Certificates and Mortgage-Backed Securities
	The Company accounts for its investments in PHC Certificates and MBS under the guidance for accounting for certain investments in debt and equity securities. The guidance requires investments in securities to be classified as one of the following: 1) held-to-maturity, 2) available-for-sale, or 3) trading securities. All of the Company's PHC Certificates and MBS investments are classified as available-for-sale, and are reported at estimated fair value with the net unrealized gains or losses reflected in other comprehensive income. Unrealized gains and losses do not affect the cash flow of the bonds, distributions to unitholders, or the characterization of the interest income of the financial obligation of the underlying collateral.
	There is no active trading market for the bonds and price quotes for the bonds are not available and the estimates of the fair values of the PHC Certificates are based on a yield to maturity analysis which begins with the current market yield rate for a “AAA” rated tax-free municipal bond for a term consistent with the weighted-average life of each of the Public Housing Capital Fund trusts adjusted largely for unobservable inputs the General Partner believes would be used by market participants. Management’s valuation encompasses judgment in its application and pricing as determined by pricing services, when available, is compared to Management's estimates.
	The Company periodically reviews each class of PHC Certificates for impairment. The Company evaluates whether a decline in the fair value of a PHC Certificate below its amortized cost is other-than temporary based on a number of factors including:
	•	The duration and severity of the decline in fair value,
	•	The Company's intent to hold and the likelihood of it being required to sell the security before its value recovers,
	•	Downgrade in the security's rating by S&P,
	•	Volatility of the fair value of the security.
	The Company values each MBS security based upon prices obtained from a third party pricing service, which are indicative of market activity. The valuation methodology of the Company's third party pricing service incorporates commonly used market pricing methods, incorporates trading activity observed in the market place, and other data inputs. The methodology also considers the underlying characteristics of each security, which are also observable inputs, including: coupon; maturity date; loan age; reset date; collateral type; geography; and prepayment speeds. Management analyzes pricing data received from the third party pricing service by comparing it to valuation information obtained from at least one other third party pricing service and ensuring they are within a tolerable range of difference which the Company estimates as 7.5%. Management also looks at observations of trading activity in the market place when available.
	The Company periodically reviews each MBS security for impairment. The Company evaluates whether a decline in the fair value of a security below its amortized cost is other-than-temporary based on a number of factors including the duration and severity of the decline in fair value and the Company's intend and ability to hold the security until its value recovers. Each MBS security has been rated either "AAA" or "AA" by either S&P or Moody's. A downgrade in rating for each MBS or new issuances of similar MBS with ratings by S&P or Moody's below the "A" rating would be a factor in concluding that an impairment is other-than-temporary.
	Investments in Real Estate
	The Company's investments in real estate are carried at cost less accumulated depreciation. Depreciation of real estate is based on the estimated useful life of the related asset, generally 19-40 years on multifamily residential apartment buildings and five to 15 years on capital improvements and is calculated using the straight-line method. Maintenance and repairs are charged to expense as incurred, while improvements, renovations, and replacements are capitalized.
	Management reviews each property for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of a property may not be recoverable. The review of recoverability is based upon comparing the net book value of each real estate property to the sum of its estimated undiscounted future cash flows. If impairment exists due to the inability to recover the carrying value of a property, an impairment loss is recorded to the extent that the carrying value of the property exceeds its estimated fair value.
	Taxable Property Loans
	In addition to the mortgage revenue bonds held by the Company, taxable property loans have been made to the owners of some of the properties which secure the bonds.  The repayment of these taxable property loans is dependent largely on the value of the property or its cash flows which collateralize the loans.  The Company periodically evaluates these loans for potential losses by estimating the fair value of the property which collateralize the loans and comparing the fair value to the outstanding mortgage revenue bonds plus any taxable property loans.  The Company utilizes the discounted cash flow model discussed above except that in estimating a property fair value we evaluate a number of different discounted cash flow ("DCF") models that contain varying assumptions.  The various models may assume multiple revenue and expense scenarios, various capitalization rates, and multiple discount rates.  The Company may also consider other information such as independent appraisals in estimating a property fair value.
	If the estimated fair value of the property after deducting the amortized cost basis of the senior mortgage revenue bond exceeds the principal balance of the taxable property loan then no potential loss is indicated and no allowance for loan loss is recorded.  If a potential loss is indicated, an allowance for loan loss is recorded against the outstanding loan amount and a loss is realized.  The determination of the need for an allowance for loan loss is subject to considerable judgment. For the years ended December 31, 2013 and 2011, the Company recognized a provision for loan losses of approximately $168,000 and $4.2 million, respectively. For the year ended December 31, 2012, the Company did not recognize any provision for loan losses.
	Accounting for Tax Exempt Bond Securitization ("TEBS") and Tender Option Bond ("TOB") Financing Arrangements
	The Company has evaluated the accounting guidance in regard to the TEBS and TOB Financing arrangements (Note 11) and has determined that the securitization transactions do not meet the accounting criteria for a sale or transfer of financial assets and will, therefore, be accounted for as a secured financing transactions. More specifically, the guidance on transfers and servicing sets forth the conditions that must be met to de-recognize a transferred financial asset. This guidance provides, in part, that the transferor has surrendered control over transferred assets if and only if the transferor does not maintain effective control over the transferred assets through any of the following:
	1	An agreement that both entitles and obligates the transferor to repurchase or redeem them before their maturity,
	2	The ability to unilaterally cause the holder to return specific assets, other than through a cleanup call, or
	3	An agreement that permits the transferee to require the transferor to repurchase the transferred financial assets at a price that is so favorable to the transferee that it is probable that the transferee will require the transferor to repurchase them.
	The TEBS financing agreements contain certain provisions that allow the Company to (1) cause the return of certain individual bonds under defined circumstances, (2) cause the return of all of the bonds by electing an Optional Series Pool Release or (3) cause the return of any defaulted bonds. The Optional Series Pool Release is defined in the agreements as two specific dates, September 15, 2017, or September 15, 2020, on which the Company has the option to repurchase all of the securitized bonds. Given these terms, the Company has concluded that the condition in item 2 above is present in the agreements and, therefore, effective control over the transferred assets has not occurred. As effective control has not been transferred, the transaction does not meet the conditions to de-recognize the assets resulting in the TEBS financing being presented on the Company's consolidated financial statements as a secured financing. The TOB Financing agreements contain certain provisions that allow the Company to call the bonds held in the tender option bond trusts ("TOB Trusts") through their ownership of the residual participating interests ("LIFERS") so effective control has not been transferred resulting in the TOB Financings being presented on the Company's consolidated financial statements as secured financings.
	In addition to evaluating the TEBS financing as a sale or transfer of financial assets, we have evaluated the securitization trust associated with the TEBS financing facility (the “TEBS Trust”) under the provisions of consolidation guidance. As part of the TEBS Financing, certain bond assets of the Partnership were securitized into the TEBS Trust with Freddie Mac. The TEBS Trust then issued Class A and B TEBS Certificates. Other Company investments are securitized into TOB Trusts with Deutsche Bank AG (“DB”). The TOB trustee then issued senior floating-rate participating interests ("SPEARS") and LIFERS. The Partnership has determined that the TEBS Trust is a VIE and the Class B Certificates owned by the Partnership create a variable interest in the TEBS Trust. It was also determined that the TOB Trusts are VIEs and the LIFERS owned by the Company create a variable interest entity in the TOB Trusts.
	In determining the primary beneficiary of the TEBS Trust and TOB Trusts, the Partnership considered the activities of each of the VIEs which most significantly impact the VIE's economic performance, who has the power to control such activities, the risks which the entity was designed to create, the variability associated with those risks and the interests which absorb such variability. The Partnership has retained the right, pursuant to the TEBS financing agreements, to either substitute or reacquire some or all of the securitized bonds at various future dates and under various circumstances. As a result, the Partnership determined it had retained a controlling financial interest in the TEBS Trust because such actions effectively provide the Partnership with the ability to control decisions pertaining to the VIE's management of interest rate and credit risk. While in the TEBS Trust, the bond assets may only be used to settle obligations of the trust and the liabilities of the trust do not provide the Class A certificate holders with recourse to the general credit of the Partnership.
	The Partnership also determined it was the primary beneficiary of the TOB Trusts as it has the right to cause each TOB trust to sell the securitized asset in each specific TOB Trust. If the securitized assets were sold, the extent to which the VIE will be exposed to gains or losses from changes in the fair market value of the securitized assets would result from decisions made by the Partnership.
It was determined that the Partnership met both of the primary beneficiary criteria and was the most closely associated with the VIE and, therefore, was determined to be the primary beneficiary under these financing arrangements. Given these accounting determinations, the TEBS financing facility and the associated TEBS Trust are presented as a secured financing within the consolidated financial statements. The TOB Financings and associated TOB trusts are also presented as a secured financing within the consolidated financial statements.
Bond Purchase Commitments
The bond purchase commitments held by the Company have no cost. However, they are required to be measured and recorded at fair value, which is estimated under the same methodology as the Company's mortgage revenue bonds in the Company's financial statements (Notes 5 and 17).
Deferred Financing Costs
Debt financing costs are capitalized and amortized on the effective interest method over the stated maturity of the related debt financing agreement. Bond issuance costs are capitalized and amortized on the effective interest method over the stated maturity of the related mortgage revenue bonds.  As of December 31, 2013 and 2012, debt financing costs and bond issuance costs of $5.3 million and $4.6 million, respectively, were included in other assets. These costs are reduced on the balance sheet by the accumulated amortization of approximately $2.8 million and $1.8 million as of December 31, 2013 and 2012, respectively.
Income Taxes
No provision has been made for income taxes because the unitholders are required to report their share of the Partnership's taxable income for federal and state income tax purposes.  Certain of the Consolidated VIEs and wholly-owned subsidiaries of the Partnership are corporations that are subject to federal and state income taxes.  At December 31, 2013 and 2012, the Company evaluated whether it was more likely than not that any deferred tax assets would be realized.  The Company has recorded a full valuation allowance of approximately $7.4 million and $10.0 million at December 31, 2013 and 2012, respectively, against the deferred tax assets created at these entities by timing differences because the realization of these future benefits is not more likely than not.
Revenue Recognition on Investments in Mortgage Revenue Bonds
The interest income received by the Partnership from its mortgage revenue bonds is dependent upon the net cash flow of the underlying properties. Base interest income on fully performing mortgage revenue bonds is recognized as it is earned. Base interest income on mortgage revenue bonds not fully performing is recognized as it is received. Past due base interest on mortgage revenue bonds, which are or were previously not fully performing, is recognized as it is received. The Partnership reinstates the accrual of base interest once the mortgage revenue bond's ability to perform is adequately demonstrated. Contingent interest income, which is only received by the Partnership if the property financed by a mortgage revenue bond that contains a contingent interest provision generates excess available cash flow as set forth in each bond, is recognized when realized or realizable. Past due contingent interest on mortgage revenue bonds, which are or were previously not fully performing, is recognized when realized or realizable. As of December 31, 2013 and 2012, the Company's mortgage revenue bonds were fully performing as to their base interest with the exception of the Woodland Park bond in 2012.
An evaluation was performed during fiscal 2011 which determined that the interest receivable accrued on the Woodland Park bond was impaired and an approximate $953,000 allowance for loss on receivables was recorded. The Partnership received two interest payments during 2012 and recorded an additional allowance of approximately $453,000 against the remaining interest receivable in 2012. The Partnership recorded an approximate additional $242,000 against the interest receivable before the mortgage revenue bond foreclosure was completed in May 2013 and title to the Woodland Park property was conveyed to a wholly-owned subsidiary of the Partnership (Note 8).
Revenue Recognition on Investments in Real Estate, MBS, and PHC Certificates
The Partnership's Consolidated VIEs and the MF Properties (Note 8) are lessors of multifamily rental units under leases with terms of one year or less. Rental revenue is recognized, net of rental concessions, on a straight-line method over the related lease term.
Interest income on the MBS and PHC Certificates is recognized as it is earned (Notes 6 and 7).
Derivative Instruments and Hedging Activities
The Company accounts for its derivative and hedging activities in accordance with the guidance on Derivatives and Hedging. The guidance on Derivatives and Hedging requires the recognition of all derivative instruments as assets or liabilities in the Company's consolidated balance sheets and measurement of these instruments at fair value. The accounting treatment is dependent upon whether or not a derivative instrument is designated as a hedge and, if so, the type of hedge.  The Company's interest rate derivative agreements do not have a specific hedge designation under the guidance on derivatives and hedging, and therefore changes in fair value are recognized in the consolidated statements of operations as interest expense.  The Company is exposed to loss should a counterparty to its derivative instruments default.  The Company does not anticipate non-performance by any counterparty.  The fair value of the interest rate derivative agreements is determined based upon current price quotes by recognized dealers.
Net Income per BUC
Net income per BUC has been calculated based on the weighted average number of BUCs outstanding during each year presented. The Partnership has no dilutive equity securities and, therefore, basic net income per BUC is the same as diluted net income per BUC.  The following table provides a reconciliation of net income per BUC holder:

Use of Estimates in Preparation of Consolidated Financial Statements
The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates and assumptions include those used in determining investment valuation, investment impairments, impairment of property assets, and allowance for loan losses.

	Partnership Income, Expenses and Cash Distributions
	The Agreement of Limited Partnership of the Partnership contains provisions for the distribution of Net Interest Income, Net Residual Proceeds and Liquidation Proceeds, for the allocation of income or loss from operations and for the allocation of income and loss arising from a repayment, sale or liquidation of investments.  Income and losses will be allocated to each unitholder on a periodic basis, as determined by the General Partner, based on the number of BUCs held by each unitholder as of the last day of the period for which such allocation is to be made. Distributions of Net Interest Income and Net Residual Proceeds will be made to each unitholder of record on the last day of each distribution period based on the number of BUCs held by each unitholder as of such date. For purposes of the Agreement of Limited Partnership, cash distributions, if any, received by the Partnership from the Investment in MF Properties (Note 8) will be included in the Partnership's Interest Income and cash distributions received by the Partnership from the sale of such properties will be included in the Partnership Residual Proceeds.
	Cash distributions are currently made on a quarterly basis but may be made on a monthly or semiannual basis at the election of AFCA 2.  On each distribution date, Net Interest Income is distributed 99% to the unitholders and 1% to AFCA 2 and Net Residual Proceeds are distributed 100% to unitholders except that Net Interest Income and Net Residual Proceeds representing contingent interest in an amount equal to 0.9% per annum of the principal amount of the mortgage revenue bonds on a cumulative basis (defined as Net Interest Income (Tier 2) and Net Residual Proceeds (Tier 2), respectively) are distributed 75% to the unitholders and 25% to AFCA 2.
	The unallocated deficit of the Consolidated VIEs is primarily comprised of the accumulated historical net losses of the Consolidated VIEs as of the date of the implementation of the guidance on consolidations. The unallocated deficit of the Consolidated VIEs and the Consolidated VIEs' net losses subsequent to that date are not allocated to the General Partner and unitholders as such activity is not contemplated by, or addressed in, the Agreement of Limited Partnership.
	The distributions paid or accrued per BUC during the fiscal years ended December 31, 2013, 2012, and 2011 were as follows:

	Variable Interest Entities
	Although each multifamily property financed with mortgage revenue bonds held by the Partnership is owned by a separate entity in which the Partnership has no equity ownership interest, the debt financing provided by the Partnership creates a variable interest in these ownership entities that may require the Partnership to report the assets, liabilities and results of operations of these entities on a consolidated basis under GAAP. Under consolidation guidance, the Partnership must make an evaluation of these entities to determine if they meet the definition of a VIE.
	At December 31, 2013, the Partnership determined that four of the entities financed by mortgage revenue bonds owned by the Partnership were held by VIEs.  These VIEs were Ashley Square, Bent Tree, Cross Creek, and Fairmont Oaks. The Partnership then determined that it is the primary beneficiary of two of these VIEs; Bent Tree and Fairmont Oaks and has continued to consolidate these entities. Effective December 1, 2013, the ownership of Lake Forest became a not-for-profit entity and Lake Forest ceased to be reported as a Consolidated VIE.
	At December 31, 2012, the Partnership determined that five of the entities financed by mortgage revenue bonds owned by the Partnership were held by VIEs.  These VIEs were Ashley Square, Bent Tree, Cross Creek, Fairmont Oaks and Lake Forest. The Partnership then determined that it is the primary beneficiary of three of these VIEs; Bent Tree, Fairmont Oaks, and Lake Forest and has continued to consolidate these entities during 2012.  At December 31, 2012, the Partnership also determined that the Exchange Accommodation Titleholder ("EAT (Maples on 97th)") was also a VIE based on the Qualified Exchange Accommodation Agreement and Master Lease Agreement between the Partnership and EAT (Maples on 97th). In February 2013, title to the Maples on 97th property transferred to the Partnership from the EAT (Maples on 97th) and the property is reported as an MF Property as of December 31, 2013.
	The Partnership does not hold an equity interest in the four VIEs and therefore, the assets of the VIEs cannot be used to settle the general commitments of the Partnership and the Partnership is not responsible for the commitments and liabilities of the VIEs.  The primary risks to the Partnership associated with the four VIEs financed by mortgage revenue bonds owned by the Partnership relate to the entities ability to meet debt service obligations to the Partnership and the valuation of the underlying multifamily apartment property which serves as bond collateral.
	The following is a discussion of the significant judgments and assumptions made by the Partnership in determining the primary beneficiary of the VIE and, therefore, whether the Partnership must consolidate the VIE.
	Consolidated VIEs
	At December 31, 2013, the Partnership determined it is the primary beneficiary of the Bent Tree and Fairmont Oaks VIEs. The capital structure of Bent Tree and Fairmont Oaks VIEs consists of senior debt, subordinated debt, and equity capital. The senior debt is in the form of a mortgage revenue bond and accounts for the majority of the VIEs' total capital. As the bondholder, the Partnership is entitled to principal and interest payments and has certain protective rights as established by the bond documents. The equity ownership in these entities is ultimately held by corporations which are owned by four individuals, three of which are related parties. Additionally, each of these properties is managed by an affiliate of the Partnership, America First Properties Management Company, LLC (“Properties Management”) which is an affiliate of the Burlington Capital Group, LLC ("Burlington").
	The Partnership lent the EAT (Maples on 97th) the necessary funds to purchase the Maples on 97th property and executed a Master Lease Agreement and Construction Management Agreement. These two agreements gave the Partnership the rights and obligations to manage the replacement property as well as the rehabilitation during the six month hold period. The Partnership determined that it was the primary beneficiary of the EAT (Maples on 97th). Based on the terms of the Master Lease Agreement, the Partnership reported the rental income and related real estate operating expenses for the Maples on 97th property during the six month holding period (August 2012 to January 2013) as an MF Property since it has all the rights and obligations of landlord for the property. In February 2013, title to the Maples on 97th property transferred to the Partnership from the EAT (Maples on 97th).
	In determining the primary beneficiary of these VIEs, the Partnership considered the activities of the VIE which most significantly impact the VIEs' economic performance, who has the power to control such activities, the risks which the entities were designed to create, the variability associated with those risks and the interests which absorb such variability. The Partnership also considered the related party relationships of the entities involved in the VIEs. It was determined that the Partnership, as part of the related party group, met both of the primary beneficiary criteria and was the most closely associated with the VIEs and, therefore, was determined to be the primary beneficiary.
	Non-Consolidated VIEs
	The Company does not consolidate two VIE entities, Ashley Square and Cross Creek. In determining the primary beneficiary of these VIEs, the Partnership considered the activities of each VIE which most significantly impact the VIEs' economic performance, who has the power to control such activities, the risks which the entities were designed to create, the variability associated with those risks and the interests which absorb such variability. The significant activities of the VIE that impact the economic performance of the entity include leasing and maintaining apartments, determining if the property is to be sold, decisions relating to debt refinancing, the selection of or replacement of the property manager and the approval of the operating and capital budgets. As discussed below, while the capital structures of these VIEs resulted in the Partnership holding a majority of the variable interests in these VIEs, the Partnership determined it does not have the power to direct the activities of these VIEs that most significantly impact the VIEs' economic performance and, as a result, is not the primary beneficiary of these VIEs.
	Ashley Square - Ashley Square Housing Cooperative acquired the ownership of the Ashley Square apartments in December 2008 from Ashley Square LLC through a warranty deed of transfer and an assumption of debt. This transfer of ownership constitutes a reconsideration event as outlined in consolidation guidance which triggers a re-evaluation of the holders of variable interests to determine the primary beneficiary of the VIE. The capital structure of the VIE consists of senior debt, subordinated loans. and equity capital. The senior debt is in the form of mortgage revenue bonds that are 100% owned by the Partnership and account for the majority of the VIE's total capital. As the bondholder, the Partnership is entitled to principal and interest payments and has certain protective rights as established by the bond documents. The VIE is organized as a housing cooperative and the 99% equity owner of this VIE is The Foundation for Affordable Housing (“FAH”), an unaffiliated Nebraska non-profit organization. Additionally, this property is managed by Properties Management.
	Cross Creek - Cross Creek Apartments Holdings LLC is the owner of the Cross Creek Apartments. On January 1, 2010, Cross Creek Apartment Holdings LLC entered into a new operating agreement and admitted three new members. These new members committed approximately $2.2 million of capital, payable in three installments including $563,000 on January 1, 2010. The new operating agreement and admission of new owner members constitutes a reconsideration event as outlined in the consolidation guidance which triggers a re-evaluation of the holders of variable interests to determine the primary beneficiary of the VIE. The capital structure of the VIE consists of senior debt, subordinated loans and equity capital at risk. The senior debt is in the form of mortgage revenue bonds that are 100% owned by the Partnership and account for the majority of the VIE's total capital. As the bondholder, the Partnership is entitled to principal and interest payments and has certain protective rights as established by the bond documents. The three newly admitted members of this VIE are each unaffiliated with the Partnership and have contributed significant equity capital to the VIE. These members collectively control a 99% interest in the VIE. The other 1% member of this VIE is FAH, which is also unaffiliated with the Partnership. Additionally, this property is managed by Properties Management.
	The following table presents information regarding the carrying value and classification of the assets held by the Partnership as of December 31, 2013 and 2012, which constitute a variable interest in Ashley Square and Cross Creek.

	5.  Investments in Mortgage Revenue Bonds
	Each of the mortgage revenue bonds were issued by various state and local governments, their agencies and authorities to finance the construction or rehabilitation of income-producing real estate properties. However, the mortgage revenue bonds do not constitute an obligation of any state or local government, agency or authority and no state or local government, agency or authority is liable on them, nor is the taxing power of any state or local government pledged to the payment of principal or interest on the mortgage revenue bonds. The mortgage revenue bonds are non-recourse obligations of the respective owners of the properties. The sole source of the funds to pay principal and interest on the mortgage revenue bonds is the net cash flow or the sale or refinancing proceeds from the properties. Each mortgage revenue bond, however, is collateralized by a mortgage on all real and personal property included in the related property and bears interest at a fixed rate and four of the mortgage revenue bonds provide for the payment of additional contingent interest that is payable solely from available net cash flow generated by the financed property.
	The mortgage revenue bonds owned by the Company have been issued to provide construction and/or permanent financing of multifamily residential properties. The carrying value of each of the Partnership's mortgage revenue bonds as of December 31, 2013 and 2012 is as follows:

Valuation - As all of the Company's investments in mortgage revenue bonds are classified as available-for-sale securities, they are carried on the balance sheets at their estimated fair values.  Due to the limited market for the mortgage revenue bonds, these estimates of fair value do not necessarily represent what the Company would actually receive in a sale of the bonds.  There is no active trading market for the bonds and price quotes for the bonds are not generally available.  As of December 31, 2013 and December 31, 2012, all of the Company's mortgage revenue bonds were valued using discounted cash flow or yield to maturity analysis performed by management.  Management's valuation encompasses judgment in its application.  The key assumption in management's yield to maturity analysis is the range of effective yields on the individual bonds.  At December 31, 2013, the range of effective yields on the individual bonds was 6.3% to 9.8% per annum.  Additionally, the Company calculated the sensitivity of the key assumption used in calculating the fair values of these bonds.  Assuming an immediate ten percent adverse change in the key assumption, the effective yields on the individual bonds would increase to a range of 6.9% to 10.8% per annum and would result in additional unrealized losses on the bond portfolio of approximately $22.1 million.  This sensitivity analysis is hypothetical and is as of a specific point in time.  The results of the sensitivity analysis may not be indicative of actual changes in fair value and should be used with caution.  If available, the general partner may also consider price quotes on similar bonds or other information from external sources, such as pricing services.  Pricing services, broker quotes and management's analysis provide indicative pricing only.
Unrealized gains or losses on these mortgage revenue bonds are recorded in accumulated other comprehensive income (loss) to reflect changes in their estimated fair values resulting from market conditions and fluctuations in the present value of the expected cash flows from the underlying properties. As of December 31, 2013, two bonds, Woodlynn Village and Vantage at Judson, have been in an unrealized loss position for greater than twelve months.  The Company has reviewed each of its mortgage revenue bonds for impairment. Based upon this evaluation, the current unrealized losses on these two bonds are not considered to be other-than-temporary. If yields on new issuance of tax-exempt investments increase, the Company experiences deterioration in the estimated fair values of its investment portfolio, or if the Company's intent and ability to hold certain bonds changes, the Company may incur impairments to its investment portfolio which could negatively impact the Company's financial condition, cash flows, and reported earnings. The Company has the intent and ability to hold both of these mortgage revenue bonds until their stated maturity.
The Avistar at Chase Hill, Avistar at the Crest, Avistar at the Oaks, Avistar in 09, Avistar on the Boulevard, Avistar on the Hills, The Suites on Paseo, Copper Gate, Renaissance, The Palms at Premier Park, Tyler Park Apartments, Vantage at Harlingen, and Westside Village Market mortgage revenue bonds were purchased in 2013 so they have been in unrealized loss positions for less than twelve months. The Greens Property A mortgage revenue bond has been reported due to the realized sale of the Greens Property in 2013, so reports an unrealized loss position for less than twelve months (Note 10). As the Lake Forest VIE was deconsolidated in 2013, the mortgage revenue bond reports an unrealized loss position for less than twelve months in 2013 (Note 4). In addition, Autumn Pines, Bella Vista, Bridle Ridge and Runnymede mortgage revenue bonds report unrealized losses for less than twelve months.
The Company's ability to recover the mortgage revenue bonds' entire amortized cost basis is dependent upon the issuer being able to meet debt service requirements.  The primary source of repayment is the cash flows produced by the property which serves as the collateral for the bonds.  The Company utilizes a discounted cash flow model for the underlying property and compares the results of the model to the amortized cost basis of the bond.  These models reflect the cash flows expected to be generated by the underlying properties over a ten year period, including an assumed property sale at the end of year ten, discounted using the effective interest rate on the bonds in accordance with the accounting guidance on other-than-temporary impairment of debt securities. The revenue, expense, and resulting net operating income projections which are the basis for the discounted cash flow model are based on judgment.
Recent Bond Activity
In December 2013, the Partnership acquired seven mortgage revenue bonds. They are as follows:
•	The Partnership purchased an approximate $5.2 million par value Series A mortgage revenue bond with a stated interest rate of 6.25% per annum secured by Copper Gate Apartments, a 128 unit multifamily complex in Lafayette, Indiana, maturing on December 1, 2029.
•	The Partnership purchased an approximate $6.1 million par value senior and an approximate $2.0 million par value subordinate mortgage revenue bonds with stated interest rates of 5.75% and 5.5% per annum, respectively. These mortgage revenue bonds are secured by Tyler Park Townhomes, an 88 unit multifamily complex in Greenfield, California. The senior mortgage revenue bond matures on January 1, 2030 and the subordinate mortgage revenue bond matures on January 1, 2016.
•	The Partnership purchased an approximate $4.0 million par value senior and an approximate $1.4 million par value subordinate mortgage revenue bonds with stated interest rates of 5.75% and 5.5% per annum, respectively. These mortgage revenue bonds are secured by Westside Village, an 81 unit multifamily complex in Shafter, California; The senior mortgage revenue bond matures on January 1, 2030 and the subordinate mortgage revenue bond matures on January 1, 2016.
•	The Partnership purchased an approximate $20.2 million par value Series A mortgage revenue bond with a stated interest rate of 6.25% per annum secured by The Palms at Premier Park Apartments, a 240 unit multifamily complex in Columbia, South Carolina. This mortgage revenue bond matures on January 1, 2050.
•	The Partnership purchased an approximate $35.8 million par value Series A mortgage revenue bond with a stated interest rate of 6.25% per annum secured by The Suites on Paseo, a 384 bed student housing project in San Diego, California. This mortgage revenue bond matures on December 1, 2048.
Effective December 1, 2013, the ownership of Lake Forest became a not-for-profit entity, a reconsideration event, and Lake Forest ceased to be reported as a Consolidated VIE. As such, the Partnership is reporting the estimated fair value of the Lake Forest mortgage revenue bond as an investment asset for the first time in 2013.
In August 2013, the Partnership acquired a mortgage revenue bond secured by the Vantage at Harlingen Apartments, a 288 unit multifamily apartment complex located in Harlingen, Texas which is under construction. The Series C bond was purchased for approximately $6.7 million par value, carries a base interest rate of 9.0% per annum, and matures on October 1, 2053. The Partnership also acquired an approximate $1.3 million subordinate taxable bond which is recorded as an Other Asset. The Vantage at Harlingen Apartments has a construction loan with an unrelated bank and the Partnership's mortgage revenue bonds are second lien borrowings to that construction loan.
Under the terms of a Forward Delivery Bond Purchase Agreement, the Partnership has agreed to purchase a new mortgage revenue bond between $18.0 million to approximately $24.7 million (“Harlingen Series B Bond”) secured by the Vantage at Harlingen apartments which will be delivered by the mortgage revenue bond issuer once the property meets specific obligations and occupancy rates. The final amount of the Series B Bond will depend on the appraisal of the stabilized property. The Harlingen Series B Bond will have a stated annual interest rate of 6.0% per annum and bond proceeds must be used to pay off the construction loan to the bank and all or a portion of the $6.7 million subordinate Series C mortgage revenue bond. The Partnership accounts for the bond purchase commitment as an available-for-sale security and, as such, records the change in the estimated fair value of the bond purchase commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.  As of December 31, 2013, the Partnership estimated the value of this Bond Purchase Commitment and recorded a liability of approximately $1.7 million.
During the first quarter of 2013, BC Partners contributed $6.5 million of capital into the Ohio Properties which allowed the Company to recognize a sale of the discontinued operations (Note 9). As such, the Partnership is reporting the estimated fair value of the Ohio Properties’ mortgage revenue bonds as assets in the consolidated balance sheet for the first time in 2013.
In July 2013, the limited partner property owner contributed approximately $800,000 of additional capital into the Greens Property which allowed the Company to recognize a sale of the discontinued operations (Note 9). As such, the Partnership is reporting the estimated fair value of the Green Property mortgage revenue bonds as an asset in the consolidated balance sheet for the first time in 2013.
In June 2013, the Partnership redeemed its interest in the Iona Lakes mortgage revenue bond for approximately $21.9 million. This redemption resulted in the realization of approximately $6.5 million in contingent interest income and approximately $4.6 million realized loss on a taxable property loan. The trust indenture for this bond had a waterfall feature which stipulated that all unpaid contingent interest must be paid prior to making payment on any taxable loan between the owner of the bond and the property.
In June 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas. The mortgage revenue bond purchases are as follows: approximately $5.9 million par value Series A and approximately $2.5 million par value Series B mortgage revenue bonds secured by the Avistar at the Oaks Apartments, a 156 unit multifamily apartment complex; approximately $3.1 million Series A and approximately $2.3 million Series B mortgage revenue bonds secured by the Avistar on the Hills Apartments, a 129 unit multifamily apartment complex; and approximately $5.5 million Series A and approximately $1.7 million Series B mortgage revenue bonds secured by Avistar in 09 Apartments, a 133 unit multifamily apartment complex. The three Series A mortgage revenue bonds each carry an annual interest rate of 6.0% per annum and mature on August 1, 2050. The three Series B mortgage revenue bonds each carry an annual base interest rate of 9.0% per annum and mature on September 1, 2050. The Partnership also acquired approximately $831,000 of taxable mortgage revenue bonds which also carry a base interest rate of 9.0% per annum and mature on September 1, 2050. The Company has determined that the entity which owns the three properties is an unrelated not-for-profit which under the accounting guidance is not subject to applying the VIE consolidation guidance. As a result, the properties' financial statements are not consolidated into the consolidated financial statements of the Company.
On May 29, 2013 the Partnership received the Sheriff's deed conveying title of the Woodland Park property to a wholly-owned subsidiary of the Partnership which settled the ongoing foreclosure of this mortgage revenue bond. Woodland Park became an MF Property upon title conveyance (Note 8). The Partnership is converting the property to a market rate rent execution to maximize its value but may look to turn it back to an affordable rental property and then seek to place new mortgage revenue bond financing on the property and acquire the bonds.
In April 2013, the Partnership acquired the Series C mortgage revenue bond secured by the Renaissance Gateway Apartments, a 208 unit multifamily apartment complex located in New Orleans, Louisiana for approximately $2.9 million par value. In the third and fourth quarters of 2013, the Partnership purchased approximately $1.3 million par value Series B and approximately $3.9 million par value Series A, respectively, mortgage revenue bonds. The Series C mortgage revenue bond carries a base interest rate of 12.0% per annum and matures on June 1, 2015. The Series A and Series B mortgage revenue bonds carry a base interest rate of 6.0% and 12.0% per annum, respectively, maturing on June 1, 2030. This property is undergoing a major rehabilitation and the Partnership has agreed to fund a total of approximately $8.6 million of a Series A mortgage revenue bond during construction which is estimated to be completed on June 30, 2014. Upon completion of construction and stabilization, the approximate $2.9 million Series C bond will be paid back on the earlier of when the property receives its final equity contribution by the limited partner or June 1, 2015. The Partnership accounts for the Bond Purchase Commitment as an available-for-sale security and, as such, records the change in estimated fair value of the Bond Purchase Commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.  As of December 31, 2013, the Partnership estimated the value of this Bond Purchase Commitment and recorded a liability of approximately $600,000.
In February 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas. The bond purchases are as follows: approximately $13.8 million par value Series A and approximately $3.2 million par value Series B mortgage revenue bonds secured by the Avistar on the Boulevard, a 344 unit multifamily apartment complex; approximately $9.0 million Series A and approximately $2.0 million Series B mortgage revenue bonds secured by the Avistar at Chase Hill, a 232 unit multifamily apartment complex; and approximately $8.8 million Series A and approximately $17.0 million Series B mortgage revenue bonds secured by Avistar at the Crest, a 200 unit multifamily apartment complex. The three Series A mortgage revenue bonds each carry an annual interest rate of 6.0% per annum and mature on March 1, 2050. The three Series B mortgage revenue bonds each carry an annual base interest rate of 9.0% per annum and mature on April 1, 2050. The Partnership also acquired approximately $804,000 of taxable mortgage revenue bonds which also carry a base interest rate of 9.0% per annum and mature on April 1, 2050. The Company has determined that the entity which owns the three Avistar properties is an unrelated not-for-profit which under the accounting guidance is not subject to applying the VIE consolidation guidance. As a result, the properties' financial statements are not consolidated into the consolidated financial statements of the Company.
In December 2012, the Partnership purchased an approximate $6.0 million subordinate mortgage revenue bond and a $934,000 subordinate taxable bond both secured by the Vantage at Judson apartments. This property is located in San Antonio, Texas and is currently under construction. Both bonds mature on February 1, 2053 and carry an annual cash interest rate of 9.0% per annum plus allow for an additional 3% per annum of interest calculated on the property's cash flows after debt service. The Vantage at Judson apartments has a construction loan with an unrelated Bank and the Partnership's bonds are second lien borrowings to that construction loan. The property will have 288 units when construction is completed in the spring of 2014. The Company has determined that the entity which owns Vantage at Judson apartments is an unrelated not-for-profit which under the accounting guidance is not subject to applying the VIE consolidation guidance. As a result, the property's financial statements are not consolidated into the consolidated financial statements of the Company.
Under the terms of a Forward Delivery Bond Purchase Agreement, the Partnership has agreed to purchase a new mortgage revenue bond of up to $26.7 million (“Series B Bonds”) which will be delivered by the mortgage revenue bond issuer once the property meets specific obligations and occupancy rates. The Series B Bonds will have a stated annual interest rate of 6.0% per annum and bond proceeds must be used to pay off the construction loan to the Bank and all or a portion of the approximately $6.0 million subordinate mortgage revenue bond. If the property does not meet its specific obligations and required occupancy rate before January 1, 2015, the Partnership has the right to terminate the purchase commitment. The Partnership accounts for the bond purchase agreement as an available-for-sale security and, as such, records the estimated value of the forward purchase commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.  As of December 31, 2013, the Partnership has estimated the value of this bond purchase commitment and recorded a liability of approximately $2.0 million. As of December 31, 2012, the Partnership had concluded there was no value to the forward purchase commitment.
In June 2012, the Partnership acquired a $10.0 million restructured par value mortgage revenue bond secured by Arbors at Hickory Ridge Apartments, a 348 unit multifamily apartment complex located in Memphis, Tennessee, which represented 100% of the bond issuance for approximately $10.2 million. The mortgage revenue bond carried an annual interest rate of 7.98% per annum and matures on April 1, 2026. The bond did not provide for contingent interest. In conjunction with the purchase of the Arbors of Hickory Ridge mortgage revenue bond, an affiliate of the Global Ministries Foundation, a not-for-profit entity unrelated to the Company acquired the multi-family property securing the bond. At closing, the Company also secured a $600,000 promissory note receivable as a fee for identifying this property acquisition and performing the related due diligence.
In December 2012, the mortgage revenue bond secured by Arbors at Hickory Ridge Apartments was restructured to an $11.5 million par value mortgage revenue bond with an annual interest rate of 6.25% per annum and maturity of December 1, 2049. The Partnership then purchased 100% of this bond issuance plus a taxable loan of approximately $191,000 for a payment of approximately $1.0 million made at closing. In connection with the closing of the restructured mortgage revenue bond, the Company received payment in full of the $600,000 promissory note less costs associated with the transaction and approximately $557,000 has been recorded as other income.
In October 2012, the Company acquired 100% of the $9.5 million mortgage revenue bonds issued by the North Carolina Housing Finance Agency as part of a plan of financing for the acquisition and rehabilitation of the Greens Property. The mortgage revenue bonds secured by the Greens Property were acquired by the Company at par and consisted of two series. The Series A bond has a par value of approximately $8.5 million and bears interest at an annual rate of 6.5% per annum. The Series B bond has a par value of approximately $1.0 million and bears interest at an annual interest rate of 12.0% per annum. Both series of bonds mature on October 1, 2047. In connection with the bond financing transaction, ownership of the Greens Property was conveyed by the Company to a new ownership entity controlled by an unaffiliated not-for-profit entity. However, because the new ownership entity did not have sufficient equity capital at the time of purchase and the property operations are the sole source of debt service on the Company's bonds, the Company is required to continue to account for the Greens Property as if it is the owner of real estate rather than as a secured lender. As such, the Company continues to report the results from the Greens Property as discontinued operations in its financial statements as of December 31, 2012 which, among other things, results in the elimination of the bonds in consolidation (Note 10).
In May 2012, the mortgage revenue bonds secured by GMF-Madison Tower Apartments and GMF-Warren/Tulane Apartments were sold for an amount greater than the outstanding principal and accrued base interest. The Company received approximately $4.1 million for the GMF-Madison Tower Apartments mortgage revenue bond and approximately $12.7 million from the GMF-Warren/Tulane Apartments mortgage revenue bond resulting in an approximate $668,000 realized gain. These mortgage revenue bonds had been acquired at par on June 1, 2011. At December 31, 2012, the Partnership still owns the taxable revenue bonds secured by these two properties. The taxable bond secured by GMF-Madison Tower Apartments carries an annual interest rate of 7.75% per annum and matures on December 1, 2019. The taxable bond secured by GMF-Warren/Tulane Apartments carries an annual interest rate of 6.5% per annum and matures on December 1, 2015. These taxable bonds were also acquired on June 1, 2011 and have an outstanding combined principal balance of $600,000 as of December 31, 2012.
The properties securing the Company's mortgage revenue bonds are geographically dispersed throughout the United States with significant concentration in San Antonio, Texas. As of December 31, 2013 and 2012, the concentration in San Antonio, Texas, as a percentage of principal outstanding, was approximately 30% and 17%. The Suites on Paseo property in San Diego, California represents 12% of the outstanding principal of the mortgage revenue bonds as of December 31, 2013.

	Public Housing Capital Fund Trust Certificates
	In July 2012, the Company purchased 100% of the LIFERs in the PHC TOB Trusts which acquired approximately $65.3 million of PHC Certificates issued by three trusts ("PHC Trusts") sponsored by DB. The assets held by the PHC Trusts consist of custodial receipts evidencing loans made to a number of public housing authorities. Principal and interest on these loans are payable by the respective public housing authorities out of annual appropriations to be made to the public housing authorities by the United States Department of Housing and Urban Development (“HUD”) under HUD's Capital Fund Program established under Quality Housing and Work Responsibility Act of 1998 (the “Capital Fund Program”). The PHC Trusts have a first lien on these annual Capital Fund Program payments to secure the public housing authorities' respective obligations to pay principal and interest on their loans. The loans payable by the public housing authorities are not debts, nor guaranteed by the United States of America or HUD. Interest payable on the public housing authority debt held by the PHC Trusts is exempt from federal income taxes. The PHC Certificates issued by each of the PHC Trusts have been rated investment grade by Standard & Poor's.
	The Company purchased the LIFERS issued by the PHC TOB Trusts for approximately $16.0 million and pledged the LIFERS to the trustee to secure certain reimbursement obligations of the Company as the holder of LIFERS. The PHC TOB Trusts also issued SPEARS of approximately $49.0 million to unaffiliated investors. The SPEARS represent senior interests in the PHC TOB Trusts and have been credit enhanced by DB. The LIFERS entitle the Company to all principal and interest payments received by the PHC TOB Trusts on the $65.3 million of PHC Certificates held by it after preferred return payments due to the holders of the SPEARS and trust costs. The SPEARS bear interest at a variable rate based on Securities Industry and Financial Markets Association (“SIFMA”).
	The Company determined that the three PHC TOB trusts are variable interest entities and that the Company was the primary beneficiary of each of the three PHC TOB trusts. As a result, the Company reports the PHC TOB Trusts on a consolidated basis and the SPEARS as debt financing. In determining the primary beneficiary of these specific VIEs, the Company considered who has the power to control the activities of the VIEs which most significantly impact their financial performance, the risks that the entity was designed to create, and how each risk affects the VIE. The indenture for the PHC TOB trusts stipulates that the Company has the sole right to cause the PHC TOB trusts to sell the PHC Certificates. If they were sold, the extent to which the VIEs will be exposed to gains or losses associated with variability in the PHC Certificates' fair value arising from changes in municipal bond market rates therefore would result from decisions made by the Company.
	The Company had the following investments in the PHC Certificates on December 31, 2013 and 2012:

		$	65,957,633		$	—			$	(568,335	)	$	65,389,298
	Valuation - As all of the Company’s investments in PHC Certificates are classified as available-for-sale securities, they are carried on the balance sheet at their estimated fair values.  Due to the limited market for the PHC Certificates, these estimates of fair value do not necessarily represent what the Company would actually receive in a sale of the certificates.  The estimates of the fair values of these PHC certificates is based on a yield to maturity analysis which begins with the current market yield rate for a “AAA” rated tax-free municipal bond for a term consistent with the weighted-average life of each of the Public Housing Capital Fund trusts adjusted largely for unobservable inputs the General Partner believes would be used by market participants which includes adjustments for the fact that the PHC Certificates investment grade rating is below "AAA". Management’s valuation encompasses judgment in its application and pricing as determined by pricing services, when available, is compared to Management's estimates.  The PHC Certificates are "AA" and "BBB" rated and the range of effective yields was 4.2% to 5.4% per annum at December 31, 2013.  Additionally, the Company calculated the sensitivity of the key assumption used in calculating the fair values of these PHC Certificates which is the yield for a new issuance of a similarly structure security.  Assuming a 10% adverse change in that key assumption, the effective yields on the individual PHC Certificates would increase to a range of 5.8% to 7.2% per annum and would result in additional unrealized losses on the PHC Certificates of approximately $2.9 million.  This sensitivity analysis is hypothetical and is as of a specific point in time.  The results of the sensitivity analysis may not be indicative of actual changes in fair value and should be used with caution.  If available, the general partner may also consider other information from external sources, such as pricing services.  The PHC Certificates have been in an unrealized loss position for more than 12 months and management has concluded that there is no other-than-temporary impairment to record as the Company has the intent and ability to hold on to PHC Certificates until either the estimated fair value rebounds or until maturity. In addition, the most recent update on the annual appropriations from HUD disclosed no significant changes in the program which means the underlying performance of the PHC Certificates will be in line with expectations until the next annual update. In addition, there have been no downgrades in the investment grade rating of any of the three PHC Certificates noted since the investment was originally acquired in July 2012.
	The following table sets forth certain information relating to the PHC Certificates held in the PHC TOB Trusts:
		Weighted Average Lives (Years)		Investment Rating	Weighted Average Interest Rate over Life		Principal Outstanding December 31, 2013
	Public Housing Capital Fund Trust Certificate I	12.75		AA-	5.33%		$	26,406,558

	7. Mortgage-Backed Securities
	Between November 2012 and April 2013, the Company executed six securitizations of MBS TOB Trusts. The Company purchased the LIFERS issued by the six MBS TOB Trusts for approximately $9.2 million.
	Each of the six MBS TOB Trusts issued SPEARS to unaffiliated investors; these SPEARS totaled approximately $34.9 million at issuance. The SPEARS represent senior interests in the MBS TOB Trusts, have been credit enhanced by DB and are recorded as debt financing in the consolidated balance sheet. The LIFERS entitle the Company to all principal and interest payments received by the MBS TOB Trust on the securitized MBS after payments due to the holders of the SPEARS and trust costs. The SPEARS bear interest at a variable rate based on Securities Industry and Financial Markets Association ("SIFMA").
	The Company determined that the six MBS TOB Trusts are variable interest entities and that the Company was the primary beneficiary of each of them. As a result, the Company reports the MBS TOB Trusts on a consolidated basis and the SPEARS as debt financing. In determining the primary beneficiary of these specific VIEs, the Company considered who has the power to control the activities of the VIEs which most significantly impact their financial performance, the risks that the entity was designed to create, and how each risk affects the VIE. The indenture for the MBS TOB Trusts stipulates that the Company has the sole right to cause the MBS TOB Trusts to sell the MBS. If they were sold, the extent to which the MBS TOB Trusts will be exposed to gains or losses associated with variability in the MBS' fair value arising from changes in municipal bond market rates therefore would result from decisions made by the Company. Interest earned on the MBS held by the six MBS TOB Trusts is exempt from federal income taxes.
	The carrying value of the Company's MBS as of December 31, 2013 and 2012 are as follows:
	Agency Rating of MBS (1)	Cost adjusted for amortization of premium		Unrealized Gain		Unrealized Loss				Estimated Fair Value at December 31, 2013

	(1) MBS are reported based on the lowest rating issued by a Rating Agency, if more than one rating is issued on the security, at the date presented.
	Valuation - The Company values each MBS based upon prices obtained from a third party pricing service, which are indicative of market activity. The valuation methodology of the Company's third party pricing service incorporates commonly used market pricing methods, incorporates trading activity observed in the market place, and other data inputs. The methodology also considers the underlying characteristics of each security, which are also observable inputs, including: coupon; maturity date; loan age; reset date; collateral type; geography; and prepayment speeds. Management analyzes pricing data received from the third party pricing service by comparing it to valuation information obtained from at least one other third party pricing service and ensuring they are within a tolerable range of difference which the Company estimates as 7.5%. Management also looks at observations of trading activity observed in the market place when available. At December 31, 2013, the range of effective yields on the individual MBS was 3.6% to 5.4% per annum.  Additionally, the Company calculated the sensitivity of the key assumption used in calculating the fair values of the MBS which is the effective yield on new issuances of similarly rated MBS.  Assuming a 10% adverse change in that key assumption, the effective yields on the MBS would increase to a range of 4.9% to 5.7% per annum and would result in additional unrealized losses on the bond portfolio of approximately $1.9 million.  This sensitivity analysis is hypothetical and is as of a specific point in time.  The results of the sensitivity analysis may not be indicative of actual changes in fair value and should be used with caution.  Pricing services and management’s analysis provide indicative pricing only. Certain of the MBS have been in an unrealized loss position for more than twelve months and management has concluded that there is no other-than-temporary impairment to record as the Company has the intent and ability to hold on to the MBS until either the estimated fair value rebounds or until maturity. In addition, there have been no downgrades to the investment grade rating levels of the MBS since their original acquisition dates.
	The MBS are backed by residential mortgage loans and interest payable from the MBS is believed and expected to be exempt from federal income taxation. Description of certain terms of the Company's MBS is as follows:
	Agency Rating of MBS	Principal Outstanding December 31, 2013		Principal Outstanding December 31, 2012		Weighted Average Maturity Date		Weighted Average Coupon Interest Rate
	"AAA"	$	22,710,000	$	12,675,000	12/9/37		4.05	%

	MF Properties
	To facilitate its investment strategy of acquiring additional mortgage revenue bonds secured by MF Properties, the Company has acquired through its various subsidiaries 99% limited partner positions in three limited partnerships and 100% member positions in six limited liability companies that own the MF Properties. The financial statements of these properties are consolidated with those of the Company.  The general partners of these partnerships are unaffiliated parties and their 1% ownership interest in these limited partnerships is reflected in the Company’s consolidated financial statements as noncontrolling interests.  The Company expects each of these MF Properties to eventually be sold either to a not-for-profit entity or in connection with a syndication of LIHTCs. The Company expects to purchase mortgage revenue bonds issued by the new property owners as part of the restructuring.  As of December 31, 2013, the Company's wholly-owned subsidiaries held interests in eight entities that own MF Properties containing a total of 1,582 rental units, one is located in Kansas, two are located in Nebraska, one is located in Kentucky, one is located in Indiana, one is located in Georgia, and two are located in Texas. One additional limited partnership, The 50/50 Student Housing at UNL, is currently under construction and is planned to be completed in the fall of 2014.
	Recent Transactions
	The Partnership, as sole bondholder, previously directed the bond trustee to file a foreclosure action on the Woodland Park mortgage revenue bond. On February 28, 2013, the court granted a Summary Judgment in the bond trustee's favor confirming that the mortgage revenue bond is senior to mechanic's liens filed on the property. Subsequently, the court ordered a sale of the Woodland Park property and on April 23, 2013, the Partnership made a bid to purchase the property for the amount of the outstanding principal and interest it is owed. The Partnership's Motion of Confirmation was approved by the court on May 2, 2013. The bond trustee assigned its right to the property to the Partnership on May 8, 2013 and the Partnership received the Sheriff's deed conveying title to a wholly-owned subsidiary of the Partnership on May 29, 2013. Woodland Park became an MF Property at a net asset value of approximately $15.7 million upon conveyance of title. The Partnership requested the mortgage revenue bond issuer to remove the LURA on the property and the units have been converted to 100% market-rate rents. The Partnership may convert the property back to a rent restricted property, and seek to place new financing on the property and acquire the mortgage revenue bonds.
	In March 2013, a wholly-owned subsidiary of the Company executed a 35-year ground lease with the University of Nebraska - Lincoln (“Lessor”) with an annual lease payment of $100. The leased property will have a mixed-use development consisting of a 1,605 stall parking garage and 475 bed student housing mixed-use project constructed on it. The Lessor will own the parking garage for which it will contribute approximately $16.7 million to its construction. The Company will own the student housing mixed-use project, The 50/50 Student Housing at the University of Nebraska - Lincoln ("The 50/50 Student Housing at UNL ") and currently estimates that construction will cost approximately $34.0 million. The Company executed a guaranteed maximum price contract with the general contractor for the construction on the mixed-use development. The Company expects to restructure its ownership of The 50/50 into a mortgage revenue bond holding after the construction is completed (which is estimated as August 1, 2014 ) and when the development has a sufficient history of operating results. The Company has secured approximately $29.8 million in financing facilities to cover the majority of the construction costs. The Company has borrowed approximately $7.2 million on this facility as of December 31, 2013 (Notes 12 and 17).
	In August 2012, the Company closed on the purchase of the Maples on 97th property, a 258 unit facility located in Omaha, Nebraska, for a purchase price of approximately $5.5 million through the execution of a Qualified Exchange Accommodation Agreement that assigned the right to acquire and own the Maples on 97th property to a wholly-owned subsidiary of a Title Company, ("EAT (Maples on 97th)"), for a period not to exceed six months. The Company lent the EAT (Maples on 97th) the necessary funds to purchase the replacement property; there was no other capital within that entity. The EAT (Maples on 97th) then executed a Master Lease Agreement and Construction Management Agreement with the Company. These two agreements gave the Company the rights and obligations to manage the replacement property as well as the rehabilitation during the six month hold period. During this six month holding period, the Partnership completed the majority of the rehabilitation of the property. At December 31, 2012 the EAT (Maples on 97th) was reported as a VIE. In February 2013, title to the Maples on 97th property transferred to the Partnership from the EAT (Maples on 97th) and the property is reported as an MF Property as of December 31, 2013.

	Total liabilities and net assets	$	5,544,534
	In March 2011, the Partnership purchased The Arboretum on Farnam Drive ("Arboretum"), a 145 unit independent senior living facility located in Omaha, Nebraska, for approximately $20.0 million plus transaction expenses of approximately $267,000 which is recorded within real estate operating expenses. The purchase price was funded through a conventional mortgage of $17.5 million and cash on hand. The mortgage payable is with Omaha State Bank, carries a 5.25% per annum fixed rate and matures on March 31, 2014.
	Between the third quarter of 2010 and June 2011, the Partnership acquired 810 Schutte Road LLC ("Eagle Village"), a 511 bed student housing facility located in Evansville, Indiana for approximately $4.2 million plus a conventional mortgage of approximately $8.9 million. The mortgage loan carries a variable interest rate of one-month LIBOR plus 2.75% per annum but will not be less than 3.5% per annum. On December 31, 2013 this rate was 4.4% per annum. This mortgage matures on June 1, 2014. The Partnership plans to operate the property as a student housing facility. Once stabilized as a student housing property, the Partnership will seek to restructure the ownership and capital structure through the sale of the property to a student housing not-for-profit entity. The Partnership anticipates it will then purchase mortgage revenue bonds issued as part of such a restructuring.
	The table below shows the unaudited pro forma condensed consolidated results of operations of the Company as if the Maples on 97th, Eagle Village, Arboretum and Woodland Park properties had been acquired at the beginning of the periods presented:
		For year ended December 31, 2013			For year ended December 31, 2012			For year ended December 31, 2011
	Revenues	$	47,562,142		$	27,128,238		$	25,354,941
	Net income (loss)	17,715,489			4,428,949			(2,078,012		)
	Net income (loss) allocated to unitholders	17,415,449			5,260,661			(941,676		)
	Unitholder's interest in net income (loss) per unit (basic and diluted)	0.4			0.14			(0.03		)
	For the year ended December 2013, Woodland Park added approximately $1.0 million in total revenue and approximately $164,000 in net loss to the Company since the foreclosure on May 29, 2013.
For the year ended December 2012, the EAT (Maples on 97th) added approximately $604,000 in total revenue and approximately $235,000 in net loss to the Company since it was acquired on August 29, 2012.
For the year ended December 2011, Eagle Village added approximately $945,000 in total revenue and approximately $257,000 net loss to the Partnership since it was acquired on June 29, 2011 and Arboretum added approximately $1.8 million in total revenue and approximately $695,000 net loss to the Partnership since it was acquired on March 31, 2011.
Consolidated VIE Properties
In addition to the MF Properties, the Company consolidates the assets, liabilities, and results of operations of the Consolidated VIEs in accordance with the guidance on consolidations.  Although the assets of the VIEs are consolidated, the Company has no ownership interest in the Consolidated VIEs other than to the extent they serve as collateral for the mortgage revenue bonds owned by the Partnership.  The results of operations of those properties are recorded by the Company in consolidation but any net income or loss from these properties does not accrue to the unitholders or the general partner, but is instead included in "Unallocated deficit of variable interest entities.”
As discussed in Note 4, as the result of the title transfer of the Maples on 97th property to the Partnership from the EAT and the merger of the entity owning Lake Forest,with a not-for-profit, these two entities are no longer consolidated as Consolidated VIEs.
The Company consolidated the following properties owned by the VIEs in continuing operations as of December 31, 2013 and 2012:

	In addition to the mortgage revenue bonds held by the Company, taxable property loans have been made to the owners of the properties which secure certain of the mortgage revenue bonds and are reported as Other Assets, net of allowance. The Company periodically, or as changes in circumstances or operations dictate, evaluates such taxable property loans for impairment. The value of the underlying property assets is ultimately the most relevant measure of the value to support the taxable property loan values. The Company utilizes a discounted cash flow model in estimating a property's fair value. A number of different discounted cash flow models containing varying assumptions are considered. The various models may assume multiple revenue and expense scenarios, various capitalization rates and multiple discount rates. In estimating the property valuation, the most significant assumptions utilized in the discounted cash flow model were the same as those discussed in Note 2 above except the discount rate used to estimate the property valuation in the current year models was 6.3% to 7.4%. The Company believes this represents a rate at which a multifamily property could obtain current financing similar to the current existing outstanding bonds. Other information, such as independent appraisals, may be considered in estimating a property fair value. If the estimated fair value of the property after deducting the amortized cost basis of any senior mortgage revenue bond exceeds the principle balance of the property loan then no potential loss is indicated and no allowance for loan loss is needed.
	On November 26, 2013, the Company executed a loan agreement with Foundation for Affordable Housing, a not-for-profit borrower, for approximately $1.6 million. The proceeds from this loan were used to fund a portion of the not-for-profit borrower’s acquisition of Abbington at Stones River, a 96 unit multifamily property located in Tennessee. The term of the loan is approximately eighteen months and the stated interest rate is 9.0% per annum.
	In August 2013, the Partnership acquired a Series C mortgage revenue bond and a forward contract to support the construction of Vantage at Harlingen Apartments in Harlingen, Texas. In conjunction with this contract, the Partnership acquired an approximate $1.3 million taxable mortgage revenue bond which carries a base interest rate of 9.0% per annum and matures on October 1, 2053. This taxable mortgage revenue bond is reported as part of the Taxable bonds at fair value in Other Assets. Please see the Fair Value Measurements footnote (Note 16) for the detailed description of the fair value estimation process for the taxable mortgage revenue bonds.
	In June 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas, Avistar at the Oaks Apartments, Avistar on the Hills Apartments, and Avistar in 09 Apartments. The Partnership also acquired approximately $831,000 of taxable mortgage revenue bonds which carry a base interest rate of 9.0% per annum and mature on September 1, 2050. These are reported as part of the Taxable bonds at fair value in Other Assets.
	In February 2013, the Partnership acquired six mortgage revenue bonds secured by three properties located in San Antonio, Texas, Avistar on the Boulevard, Avistar at Chase Hill, and Avistar at the Crest. The Partnership also acquired approximately $804,000 of taxable mortgage revenue bonds which carry a base interest rate of 9.0% per annum and mature on April 1, 2050. These are reported as part of the Taxable bonds at fair value in Other Assets.
	In June 2013, the Partnership redeemed its interest in the Iona Lakes mortgage revenue bond for approximately $21.9 million. This redemption resulted in the realization of approximately $6.5 million in contingent interest income and approximately $4.6 million realized loss on taxable property loans.
	During 2012, the Company purchased a taxable bond with a par value of $934,000 in conjunction with the purchase of the Vantage at Judson mortgage revenue bond and recorded a taxable loan of approximately $191,000 in conjunction with the purchase of the restructured Arbors at Hickory Ridge mortgage revenue bond. The $191,000 Arbors taxable loan has an interest rate of 6.25% and scheduled monthly principal payment over approximately two years commencing on February 2, 2014. The $934,000 Vantage at Judson taxable bond has an cash interest rate of 9.0% and requires monthly principal payments commencing in February 2016 with a term date of February 2, 2053.

	The Partnership received the Sheriff's deed conveying title of Woodland Park to a wholly-owned subsidiary of the Partnership on May 29, 2013. Woodland Park is now reported as an MF Property and the approximate $1.3 million fully allowed taxable property loan was written off (Note 8).
	The Partnership deconsolidated the VIE that owns the Lake Forest property during 2013 (Note 4).
	In conjunction with the purchase of the mortgage revenue bond secured by The Palms at Premier Park Apartments the Company purchased a parcel of land for approximately $1.1 million. The Company is holding this land as an asset available for sale reported in Other Assets at December 31, 2013.
	During 2013, the Partnership advanced additional funds to Ashley Square, Cross Creek, the Greens Property and the Ohio Properties of approximately $184,000, $233,000, $26,000 and $42,000, respectively. Due to the recognized sale of the Ohio and Greens Properties and the change in ownership of Lake Forest, the taxable property loans receivable with the Ohio and Greens Properties and Lake Forest are no longer eliminated upon consolidation (Notes 4 and 10). During 2013, the Partnership recorded loan loss reserves equal to the accrued interest on the Ashley Square, Cross Creek, Greens and the Ohio Properties taxable property loans receivable because the Partnership has determined they are not reasonably assured.
	During 2012, the Partnership advanced additional funds to Ashley Square, Cross Creek, and Iona Lakes of approximately $108,000, $150,000 and $402,000, respectively. In addition, Cross Creek paid approximately $330,000 during 2012 which was applied against the loan receivable.
	The 2011 taxable loans impairment evaluations resulted in the Partnership recording a $4.2 million loan loss reserve against the Iona Lakes taxable loan; this taxable loan and related accrued interest were written off in 2013 when the Iona Lakes mortgage revenue bond was redeemed. There were no loan loss impairments reported for the 2012 year. The Partnership also reserved against the $168,000 advanced to the Cross Creek property in 2013 based on the impairment analysis.
	The following is a detail of loan loss reserves for the years ended December 31:
			2013				2012				2011

	Balance, end of year		$	13,218,291			$	18,134,902			$	16,782,918
	Accrued interest not recognized represents interest accrued that the Partnership has determined they are not reasonably assured of collecting. During 2013, the Partnership recorded loan loss reserves equal to the accrued interest on the Ashley Square, Cross Creek, the Greens Property, Iona Lakes, Lake Forest, the Ohio Properties and Woodland Park property loans. During 2012 and 2011, the Partnership recorded loan loss reserves equal to the accrued interest on the Ashley Square, Cross Creek, Iona Lakes and Woodland Park property loans.
	The Company, at December 31, 2013 and 2012, holds an asset held for sale valued at an appraised value of $375,000, along with a receivable of approximately $711,000 representing amounts due from a project owner of Prairebrook Village. In 2008 the Company foreclosed on the Prairebrook Village bond and obtained a summary judgment against ownership. The Partnership placed liens on assets identified and garnished wages from the judgment parties.

	Discontinued Operations
	In June 2010, the Company completed a sales transaction whereby the Ohio Properties were sold to three new ownership entities controlled by an unaffiliated not-for-profit entity and in October 2011, the three limited partnerships that own the Ohio Properties admitted two entities that are affiliates of BC Partners as new limited partners as part of a syndication of LIHTCs. The BC Partners agreed to contribute equity to these limited partnerships, subject to the Ohio Properties meeting certain debt service coverage ratios specified in the applicable limited partnership agreements. As such, there was not sufficient equity invested at closing by the not-for-profit or BC Partners into the Ohio Properties to allow the Company to recognize a real estate sale for accounting purposes. During the first quarter of 2013, BC Partners contributed $6.5 million of capital into the Ohio Properties which was sufficient to allow the Company to recognize the sale for accounting purposes. This gain on sale of discontinued operations was approximately $1.8 million. The sale of this discontinued operation allowed the Company to begin reporting the mortgage revenue bonds related to the Ohio Properties as assets beginning with the March 31, 2013 consolidated financial statements.
	The deposit method of accounting for real estate sales required both the deferral of the gain from the real estate sale and also did not allow recognition of the interest payments by the Ohio Properties to the Company between June 2010 and the date of the equity contribution by BC Partners. In conjunction with the recognition of the real estate sale, approximately $3.5 million of interest has been recognized within investment income during 2013 which represents the interest payments received from the Ohio Properties between June 2010 and December 2012. In addition, the Partnership reported approximately $1.1 million in taxable note interest income received from the Ohio Properties and $250,000 guarantee fee from the general partner of the Ohio Properties during the first quarter of 2013 (Note 2). The net fixed assets and total assets of the Ohio Properties were zero at December 31, 2013 and approximately $18.6 million and $20.4 million at December 31, 2012, respectively. The deposit method of accounting also deferred the recognition of the sale of the Ohio Properties and the purchase of the mortgage revenue bonds they secure in the consolidated statement of cash flows. As such, these transactions are being recognized in the consolidated statement of cash flows in the year ending December 31, 2013.
	In October 2012, the limited partnership that owns the Greens Property admitted two entities that are affiliates of BC Partners as new limited partners as part of a syndication of LIHTCs on the Greens Property. Prior to the execution of the admittance of the new limited partners, the Company had entered into an agreement to sell the Greens Property for approximately $7.3 million to an unaffiliated not-for-profit which is the general partner of the limited partnership that now owns the Greens Property.  That sale was conditional on securing the mortgage revenue bond and low-income housing tax credits from the North Carolina Housing Finance Agency.  The $961,000 BC Partners equity contribution made into this limited partnership in October 2012 was not sufficient to allow the Company to recognize a real estate sale for accounting purposes. In July 2013, BC Partners made their required $800,000 capital contribution into the Greens Property as construction was 75% complete.
	The Company purchased 100% of the mortgage revenue bonds issued as part of the agreement to finance the acquisition and rehabilitation of the Greens Property. The Series A mortgage revenue bond has approximately $8.5 million par value and bear interest at 6.5% per annum. The Series B mortgage revenue bond has a $950,000 par value and bears interest at 12.0% per annum. Both series of mortgage revenue bonds mature in October 1, 2047. The Company also obtained an $850,000 taxable property loan secured by the Greens Property at closing.  The deposit method of accounting deferred the recognition of the sale of the Greens Property and the purchase of the mortgage revenue bonds it secures in the consolidated statement of cash flows. As such, these transactions are being recognized in the consolidated statement of cash flows in the year ending December 31, 2013.
	The July 2013 equity payment provided sufficient invested equity to recognize a real estate sale for accounting purposes and the Company recorded the sale of this discontinued operation. This gain on sale of discontinued operations was approximately $1.4 million. The deposit method of accounting for real estate sales required both the deferral of the gain from the real estate sale and also did not allow recognition of the interest payments by the Greens Property to the Company between October 2012 and the July 2013, the date of the second equity contribution by BC Partners. In conjunction with the recognition of the real estate sale, approximately $523,000 of interest has been recognized within investment income during 2013 which represents the interest payments received from the Greens Property between October 2012 and July 31, 2013. The net fixed assets and total assets of the Greens Property were zero at December 31, 2013 and approximately $8.4 million and $12.2 million at December 31, 2012, respectively.
	The Eagle Ridge property sale was completed in November 2012 and resulted in the property being reported as a discontinued operation for all periods reported. The net fixed assets and total assets of the Eagle Ridge property were approximately $2.3 million and $2.3 million at December 31, 2011. The proceeds from the sale of the property was approximately $2.5 million resulting in a gain of approximately $126,000.
	In August 2012, the Commons at Churchland property was sold for proceeds of approximately $8.1 million resulting in a gain of approximately $1.3 million. The net fixed assets and total assets of the Churchland property were approximately $6.5 million and $7.3 million at December 31, 2011.
	There were no assets and liabilities of discontinued operations to report at December 31, 2013.

	(1) Avistar at the Oaks Apartments, Avistar on the Hills Apartments, and Avistar in 09 Apartments is the collateral for the $20.0 million TOB Trust.
	(2) Avistar at Chase Hill, Avistar at the Crest, and Avistar on the Boulevard is the collateral for the approximate $13.2 million TOB Trust.
	In July 2011, the Company executed a Master Trust Agreement with DB which allows the Company to execute multiple Tender Option Bond ("TOB Trust") structures upon the approval and agreement of terms by DB. Under each TOB Trust structure issued through the Master Trust Agreement, the TOB trustee issues SPEARS and LIFERS. Theses SPEARS and LIFERS represent beneficial interests in the securitized asset held by the TOB trustee. The Company will purchase the LIFERS from each of these TOB Trusts which will grant them certain rights to the securitized assets. The Master Trust Agreement with DB has covenants with which the Company is required to maintain compliance. At December 31, 2013, the most restrictive covenant was that cash available to distribute for the trailing twelve months must be at least two times trailing twelve month interest expense. The Company was in compliance with all of these covenants as of December 31, 2013. If the Company were to be out of compliance with any of these covenants, it would trigger a termination event of the financing facilities. The Company expects to renew each of the TOB financing facilities for another one year term at its discretion per the terms of the agreements. DB can require the posting of cash collateral under the terms of the Master Trust Agreement.
	In December 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing The Suites on Paseo Series A mortgage revenue bond. The amount borrowed was approximately $25.8 million with a variable interest rate tied to SIFMA. The facility matures in December 2014. On the date of the closing the total fixed TOB Trust fee was approximately 1.6% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.4% per annum resulting in a total cost of borrowing of approximately 2.0% per annum. The outstanding balance remains at approximately $25.8 million on December 31, 2013.
	In October 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Avistar at the Oaks Apartments, the Avistar on the Hills Apartments, and the Avistar in 09 Apartments Series A mortgage revenue bonds. The amount borrowed was approximately $13.2 million with a variable interest rate tied to SIFMA. The facility matures in October 2014. On the date of the closing the total fixed TOB Trust fee was approximately 1.8% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.4% per annum resulting in a total cost of borrowing of approximately 2.2% per annum. The outstanding balance remains at $13.2 million on December 31, 2013.
	In June 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Avistar on the Boulevard, Avistar at Chase Hill, and Avistar at the Crest Series A mortgage revenue bonds. The amount borrowed was $20.0 million with a variable interest rate tied to SIFMA. The facility matures in June 2014. On the date of closing the total fixed TOB Trust fee was approximately 2.1% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.4% per annum resulting in a total cost of borrowing of approximately 2.5% per annum. During the fourth quarter 2013 the total fixed TOB Trust fee was reduced to approximately 1.8% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.4% per annum resulting in a total cost of borrowing of approximately 2.2% per annum. The outstanding balance remains at $20.0 million on December 31, 2013.
	In March 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Arbors at Hickory Ridge mortgage revenue bond. The amount borrowed was $7.0 million with a variable interest rate tied to SIFMA maturing in February 2014. On the date of closing the total fixed TOB Trust fee was approximately 2.1% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.5% per annum resulting in a total cost of borrowing of approximately 2.6% per annum. During the fourth quarter 2013 the total fixed TOB Trust fee was reduced to approximately 1.8% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.6% per annum resulting in a total cost of borrowing of approximately 2.4% per annum. The outstanding balance remains at $7.0 million on December 31, 2013.
	In February 2013, the Company executed a new TOB Trust under its credit facility with DB securitizing the Greens Property mortgage revenue bond. The amount borrowed was approximately $5.8 million with a variable interest rate tied to SIFMA maturing in December 2013. On the date of closing the total fixed TOB trust fee was approximately 2.1% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.5% per annum resulting in a total cost of borrowing of approximately 2.6% per annum. During the fourth quarter 2013 the total fixed TOB Trust fee was reduced to approximately 1.8% per annum and the variable rate paid on the TOB Trust on the SPEARS was approximately 0.6% per annum resulting in a total cost of borrowing of approximately 2.4% per annum. The outstanding balance was $5.7 million on December 31, 2013.
	In the fourth quarter of 2012 through the second quarter of 2013, the Company purchased the LIFERS issued by the trustee over six additional TOB Trusts. The LIFERS entitle the Company to all principal and interest payments received by these TOB Trusts on the mortgage-backed securities after payments due to the holders of the SPEARS and trust costs ("MBS TOB Trusts"). The SPEARS represent senior interests in the MBS TOB Trusts and some have been credit enhanced by DB. The Company reports the MBS TOB Trusts on a consolidated basis as it has determined it is the primary beneficiary of these variable interest entities (Note 6). A summary of the six MBS TOB Trusts are as follows:
	•	During fourth quarter of 2012, the Company purchased approximately $6.5 million of LIFERS from securitized MBS TOB Trusts with a par value of approximately $31.6 million of MBS. The MBS TOB Trusts also issued SPEARS of approximately $25.1 million to unaffiliated investors. The approximate outstanding amount at December 31, 2013 is $24.1 million which mature in April 2014. On the date of closing the total fixed TOB Trust fee was approximately 0.9% per annum and the variable rate paid on the SPEARS of approximately 0.3% per annum is tied to SIFMA which results in the total cost of borrowing of approximately 1.2% per annum.
	•	In January 2013, the Company purchased an additional $540,000 of LIFERS from one of the five MBS TOB Trusts which is a securitization of MBS with a par value of $2.5 million. SPEARS of approximately $2.0 million were issued by the MBS TOB Trust which is currently outstanding at December 31, 2013. This MBS TOB Trust matures in April 2014. On the date of closing the total fixed TOB Trust fee was approximately 0.9% per annum and the variable rate paid on the SPEARS of approximately 0.3% per annum is tied to SIFMA which results in the total cost of borrowing of approximately 1.2% per annum.
	•	In April 2013, the Company purchased approximately $2.2 million of LIFERS issued by a new MBS TOB Trust which is the securitization of MBS with a par value of approximately $10.0 million. The MBS TOB Trusts issued SPEARS of approximately $7.8 million to unaffiliated investors which is the outstanding amount at December 31, 2013. This facility matures in February 2014. On the date of closing the total fixed TOB Trust fee was approximately 0.9% per annum and the variable rate paid on the SPEARS of approximately 0.1% per annum is tied to SIFMA which results in the total cost of borrowing of approximately 1.0% per annum.
	As of December 31, 2013, the Company has posted approximately $4.1 million of cash collateral in connection with the six MBS TOB Trusts. This collateral is recorded as restricted cash in the consolidated financial statements.
	In July 2012, the Company purchased the PHC Certificate LIFERS issued by the PHC TOB Trusts for approximately $16.0 million and pledged the LIFERS to the trustee to secure certain reimbursement obligations of the Company as the holder of LIFERS. The Company is consolidating the PHC TOB Trust as it has determined it is the primary beneficiary of these variable interest entities. The PHC TOB Trusts issued SPEARS of approximately $49.0 million to unaffiliated investors. The SPEARS represent senior interests in the PHC TOB Trusts and have been credit enhanced by DB. The LIFERS entitle the Company to all principal and interest payments received by the PHC TOB Trusts on the $65.3 million of PHC Certificates held by it after payments due to the holders of the SPEARS and trust costs. The amount owed to the SPEARS owners is approximately $49.0 million at December 31, 2013. As of December 31, 2013, the Company has posted approximately $400,000 of cash collateral in connection with one of the PHC TOB Trusts which is recorded as restricted cash.
	As of December 31, 2013 and 2012, the total cost of borrowing for the PHC Certificates TOB financing facilities was approximately 2.3% and 2.3% per annum, respectively, and the weighted average cost of borrowing on the TOB financing facilities securitizing mortgage-backed securities was approximately 1.3% and 1.3% per annum, respectively. The Company's total cost of borrowing under the TOB financing facilities collateralized by the mortgage revenue bonds is approximately 2.7% and 1.9% per annum as of December 31, 2013 and 2012, respectively. The Company is accounting for these TOB transactions as secured financing arrangements.
	TEBS Financing
	As of September 1, 2010, the Partnership and its Consolidated Subsidiary ATAX TEBS I, LLC, entered into a number of agreements relating to a new long-term debt financing facility provided through the securitization of thirteen mortgage revenue bonds owned by the ATAX TEBS I, LLC (the “Sponsor”) pursuant to the TEBS Financing. The TEBS financing facility essentially provides the Partnership with a long-term variable-rate debt facility at interest rates reflecting prevailing short-term tax-exempt rates.
	Effective September 1, 2010, the Partnership transferred the following mortgage revenue bonds to ATAX TEBS I, LLC, a special purpose entity controlled by the Partnership pursuant to the TEBS Financing. The par value of the mortgage revenue bonds included in this financing facility as of December 31, 2013 and 2012 are as follows:

(1) Collateralized by Crescent Village, Post Woods and Willow Bend which are eliminated upon consolidation (Note 3)
The securitization of these mortgage revenue bonds occurred through two classes of certificates. The Class A TEBS Certificates were issued in an initial principal amount of $95.8 million and were sold through a placement agent to unaffiliated investors. The Class B TEBS Certificates were issued in an initial principal amount of $20.3 million and were retained by the Sponsor. The holders of the Class A TEBS Certificates are entitled to receive regular payments of interest from Freddie Mac at a variable rate which resets periodically based on the weekly Securities Industry and Financial Markets Association (“SIFMA”) floating index rate plus certain credit, facility, remarketing and servicing fees (the “Facility Fees”). As of December 31, 2013, the SIFMA rate was equal to 0.10% per annum resulting in a total cost of borrowing of 2.00% per annum on the outstanding balance on the TEBS financing facility of $93.0 million. As of December 31, 2012, the SIFMA rate was equal to 0.13% per annum resulting in a total cost of borrowing of 2.03% per annum on the outstanding balance on the TEBS financing facility of $94.0 million.
Payment of interest on the Class A TEBS Certificates will be made from the interest payments received by Freddie Mac from the Bonds and Senior Custody Receipts held by Freddie Mac on designated interest payment dates prior to any payments of interest on the Class B TEBS Certificates held by the Sponsor. As the holder of the Class B TEBS Certificates, the Sponsor is not entitled to receive interest payments on the Class B TEBS Certificates at any particular rate, but will be entitled to all payments of principal and interest on the Bonds and Senior Custody Receipts held by Freddie Mac after payment of principal and interest due on the Class A TEBS Certificates and payment of all Facility Fees and associated expenses. Accordingly, the amount of interest paid to the Sponsor on the Class B TEBS Certificates is expected to vary over time, and could be eliminated altogether, due to fluctuations in the interest rate payable on the Class A TEBS Certificates, Facility Fees, expenses and other factors.
The term of the TEBS financing facility coincides with the terms of the assets securing the TEBS Certificates, except that the Partnership may terminate the TEBS financing facility at its option on either September 15, 2017 or September 15, 2020. Should the Partnership not elect to terminate the TEBS financing facility on these dates, the full term of the TEBS financing facility runs through the final principal payment date associated with the securitized bonds, or July 15, 2050. The TOB Financing facilities mature between August 15, 2014 and December 15, 2014 with options available for the Company to extend another year.
The Company's aggregate borrowings as of December 31, 2013 contractually mature over the next five years and thereafter as follows:
2014	$	165,378,000
2015	1,139,000

	In September 2013, the Partnership executed a $7.0 million promissory note related to the Woodland Park property. This promissory note carries a fixed interest rate of approximately 2.8% per annum plus 30-day London Interbank Offered Rate ("LIBOR") which was approximately 0.2% per annum resulting in approximately 3.0% per annum at the date of closing. The Partnership has borrowed approximately $6.0 million as of December 31, 2013.
	In April 2013, the Company executed an interest-only loan to borrow up to $25.5 million for a three year term at a variable interest rate secured by The 50/50 Student Housing at UNL mixed-use project in Lincoln, Nebraska. The Company also secured a $4.3 million tax-incremental financing loan which is for a term of five years, carries a fixed interest rate of approximately 4.7% per annum, requires principal payments commencing after 24 months and has a balloon payment due at maturity. The Company has borrowed approximately $7.2 million on the three year term facility as of December 31, 2013 (Notes 7 and 16).
	In February 2013, the Partnership obtained a $7.5 million loan secured by the Maples on 97th property.

	The Partnership expects each of the MF Properties to eventually be sold either to a not-for-profit entity or in connection with a syndication of LIHTCs. The proceeds from such sale will be utilized to retire any associated outstanding mortgage loan. Should a mortgage loan reach maturity prior to a sale of the associated MF Property, the Partnership would either seek to refinance such mortgage loan or utilize cash reserves to retire the loan. The Partnership expects to provide mortgage revenue bonds as part of an overall plan of financing the acquisition of a MF Property by a new property owner.

	A substantial portion of the Partnership's general and administrative expenses and certain costs capitalized by the Partnership are paid by AFCA 2 or an affiliate and are reimbursed by the Partnership. The capitalized costs are typically incurred in connection with the acquisition or reissuance of certain mortgage revenue bonds, acquisition of PHC Certificates and MBS, debt financing transactions, and other capital transactions. The amounts in the following table represent cash payments to reimburse AFCA 2 or an affiliate for such expenses.

	AFCA 2 is entitled to receive an administrative fee from the Partnership equal to 0.45% per annum of the outstanding principal balance of any of its mortgage revenue bonds, taxable loans collateralized by real property, and other investments for which the owner of the financed property or other third party is not obligated to pay such administrative fee directly to AFCA 2. For the years ended December 31, 2013, 2012, and 2011, the Partnership paid administrative fees to AFCA 2 of approximately $1.5 million, $948,000, and $795,000, respectively.  In addition to the administrative fees paid directly by the Partnership, AFCA 2 receives administrative fees directly from the owners of properties financed by certain of the mortgage revenue bonds held by the Partnership.  These administrative fees also equal 0.45% per annum of the outstanding principal balance of these mortgage revenue bonds and totaled approximately $144,000, $133,000, and $160,000, in 2013, 2012, and 2011, respectively. Additionally, in connection with the sale of Eagle Ridge, the property paid accrued and deferred administrative fees to AFCA2 totaling approximately $71,000 in 2012. Although these third party administrative fees are not Partnership expenses, they have been reflected in the accompanying consolidated financial statements of the Company as a result of the consolidation of the VIEs.  Such fees are payable by the financed property prior to the payment of any contingent interest on the mortgage revenue bonds secured by these properties.  If the Partnership were to acquire any of these properties in foreclosure, it would assume the obligation to pay the administrative fees relating to mortgage revenue bonds on these properties.
	AFCA 2 earns mortgage placement fees in connection with the acquisition of mortgage revenue bonds by the Company.  These mortgage placement fees were paid by the owners of the respective property or the third party seller of the respective bonds and, accordingly, have not been reflected in the accompanying consolidated financial statements because these properties are not considered Consolidated VIEs. During 2013, AFCA 2 earned mortgage placement fees of approximately $2.0 million related to the 2013 mortgage revenue bond and MBS purchases.
	In 2012, the Company executed an investment placement agreement with AFCA 2 in connection with the Company's acquisition of the PHC Certificates. AFCA 2 received a fee of $653,000 in July 2012 from the Company in connection with this agreement which was recorded into the cost basis of the PHC Certificates and is being amortized against interest income on an effective yield basis. The Company executed separate investment placement agreements with AFCA 2 in connection with the Company's acquisition of the Arbors at Hickory Ridge mortgage revenue bond and the acquisition of mortgage-backed securities. In connection with the Arbors of Hickory Ridge bond placement agreement, AFCA 2 received an origination fee of $100,000 which has been recorded into the cost basis of the mortgage revenue bond and is being amortized against interest income on an effective yield basis. In connection with the mortgage-backed securities agreement, AFCA 2 received an origination fee of approximately $316,000 which has been recorded into the cost basis of the mortgage-backed securities and is being amortized against interest income on an effective yield basis. These investment placement fees are consistent with the mortgage placement fees that AFCA 2 has earned in connection with the acquisition of mortgage revenue bonds by the Company. Investment/mortgage placement fees earned by AFCA 2 totaled approximately $1.2 million, $1.4 million, and $407,000, in 2013, 2012, and 2011, respectively.
	The Partnership executed a Developer and Construction Management Agreement with two affiliates of AFCA 2 during the second quarter of 2013 in connection with the mixed-use development at the University of Nebraska - Lincoln (Note 8). These affiliates received approximately $672,000 in the first twelve months of 2013 under the terms of this Agreement. An affiliate of AFCA 2 acts as a placement advisor to the borrowers under the mortgage revenue bonds at the time they are acquired by the Company.  Any and all advisory fees are paid by the borrower of the respective bonds and, accordingly, have not been reflected in the accompanying consolidated financial statements.
	An affiliate of AFCA 2, America First Property Management Company, L.L.C. (“Properties Management”) was retained to provide property management services for Iona Lakes (bond sold in 2013), Bent Tree, Lake Forest, Fairmont Oaks, DeCordova, Eagle Ridge, Crescent Village, Maples on 97th, Meadowview, Willow Bend, Post Woods I, Post Woods II, Churchland, Glynn Place, Greens at Pine Glen, Ashley Square, Clarkson College (bond retired in May 2011), Cross Creek, and Woodland Park. The management fees paid to Properties Management amounted to approximately $1.2 million in 2013, $1.2 million in 2012, and $1.1 million in 2011. For the Consolidated VIEs, these management fees are not Partnership expenses but are recorded by each applicable VIE entity and, accordingly, have been reflected in the accompanying consolidated financial statements. Such fees are paid out of the revenues generated by the properties owned by the Consolidated VIEs prior to the payment of any interest on the mortgage revenue bonds and taxable loans held by the Partnership on these properties. For the MF Properties, these management fees are considered real estate operating expenses.
	The owners of two limited-purpose corporations which own apartment properties financed with mortgage revenue bonds and taxable loans held by the Company are employees of Burlington who are not involved in the operation or management of the Company and who are not executive officers or managers of Burlington.

Interest Rate Derivative Agreements [Abstract]	'

	Interest Rate Derivatives
	As of December 31, 2013, the Company has four derivative agreements in order to mitigate its exposure to increases in interest rates on its variable-rate debt financing and mortgages payable. The terms of the derivative agreements are as follows:
				Effective		Maturity	Purchase
	Date Purchased	Notional Amount		Capped Rate		Date	Price		Counterparty
	2-Sep-10	$	31,936,667	3	%	1-Sep-17	$	921,000	Bank of New York Mellon
	2-Sep-10	$	31,936,667	3	%	1-Sep-17	$	845,600	Barclays Bank PLC
	2-Sep-10	$	31,936,667	3	%	1-Sep-17	$	928,000	Royal Bank of Canada
	August 15, 2013	$	93,305,000	1.5	%	September 1, 2017	$	793,000	Deutsche Bank AG
	On July 30, 2013, the Company purchased a new interest rate derivative with a notional amount of $93.3 million which represents the amount outstanding on the TEBS Financing facility at August 1, 2013.  The maturity date of this interest rate derivative is September 1, 2017 and the effective capped interest rate is 1.5% per annum.  On July 30, 2013, the Company also sold a new interest rate derivative to the same counterparty which had the same notional amount of $93.3 million and an effective capped interest rate of 3.0% per annum.  The total cost of these two interest rate derivatives was approximately $800,000 and the derivative contracts do not qualify for hedge accounting, therefore, changes in the estimated fair value of the interest rate derivatives are included in earnings.  This interest rate corridor transaction effectively reduced the capped interest rate from 3.0% to 1.5% per annum on the TEBS Financing facility through the maturity date of the interest rate derivative contracts. In August 2013, the Company executed a master netting agreement with DB, which is the counterparty to these interest rate derivative contracts and is also the provider of the Company's TOB financing facilities. The Company was refunded $500,000 of posted cash collateral on the TOB financing facilities back upon the execution of this master netting agreement. There are no amounts reported on a net basis related to the Company's interest rate derivative contracts as of December 31, 2013 or 2012.
	The Company had previously entered into interest rate cap agreements with Barclays Bank PLC, Bank of New York Mellon and Royal Bank of Canada, each in an initial notional amount of approximately $31.9 million which effectively limits the interest payable by the Company on the TEBS financing facility to a fixed rate of 3.0% per annum on the combined notional amounts of the interest rate cap agreements through August 2017. The interest rate cap plus the Facility Fees payable to Freddie Mac result in a maximum potential cost of borrowing on the TEBS financing facility of 4.9% per annum.
	These interest rate derivatives do not qualify for hedge accounting and, accordingly, they are carried at fair value, with changes in fair value included in current period earnings within interest expense. Interest rate derivative expense, which is the result of marking the interest rate derivative agreements to fair value, resulted in an increase of approximately $284,000 in interest expense for the year ended December 31, 2013, as compared to an increase of approximately $900,000 in interest expense for the year ended December 31, 2012. These interest rate derivatives are presented on the balance sheet in Other Assets.  The carrying value of these derivatives was approximately $888,000 and $379,000 as of December 31, 2013 and 2012, respectively.

Fair Value Measurements [Abstract]	'
Fair Value Disclosures [Text Block]	'
	Fair Value of Financial Instruments
	Existing fair value guidance defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The guidance on fair value measurements:
	•	Defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date; and
	•	Establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date.
	Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk.  To increase consistency and comparability in fair value measurements and related disclosures, the fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels.  The three levels of the hierarchy are defined as follows:
	•	Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.
	•	Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
	•	Level 3 inputs are unobservable inputs for asset or liabilities.
	The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	Following is a description of the valuation methodologies used for assets and liabilities measured at fair value.
	Investments in Mortgage Revenue Bonds.  The fair values of the Company's investments in mortgage revenue bonds have each been based on a discounted cash flow and yield to maturity analysis performed by the General Partner.  There is no active trading market for the bonds and price quotes for the bonds are not available.  If available, the General Partner may also consider price quotes on similar bonds or other information from external sources, such as pricing services.  The estimates of the fair values of these bonds, whether estimated by the Company or based on external sources, are based largely on unobservable inputs the General Partner believes would be used by market participants.  Additionally, the calculation methodology used by the external sources and the Company encompasses the use of judgment in its application. To validate changes in the fair value of the Company's investments in mortgage revenue bonds between reporting periods, management looks at the key inputs such as changes in the current market yields on similar bonds as well as changes in the operating performance of the underlying property serving as collateral for each bond. We validate that the changes in the estimated fair value of the mortgage revenue bonds move with the changes in these monitored factors. Given these facts the fair value measurement of the Company’s investment in mortgage revenue bonds is categorized as a Level 3 input. The approximately $4.9 million estimated fair market value adjustment - mortgage bond purchase commitment liability is also categorized as a Level 3 input. This unrealized loss was recorded in other comprehensive income (loss) during the year ended December 31, 2013.
	Investment in Public Housing Capital Fund Trust Certificates. The fair value of the Company’s investment in Public Housing Capital Fund Trust Certificates has been based on a yield to maturity analysis performed by the General Partner. There is no active trading market for the trusts' certificates owned by the Company but the General Partner will look at estimated values as determined by pricing services when available. The estimates of the fair values of these trusts' certificates begin with the current market yield rate for a “AAA” rated tax-free municipal bond for a term consistent with the weighted-average life of each of the Public Housing Capital Fund trusts adjusted largely for unobservable inputs the General Partner believes would be used by market participants. Additionally, the calculation methodology used by external pricing services and the Company encompasses the use of judgment in its application. We validate that the changes in the estimated fair value of Public Housing Capital Fund Trust Certificates move with the changes in the market yield rates of investment grade rated tax-exempt municipal bonds with similar length of terms. Given these facts the fair value measurement of the Company’s investment in Public Housing Capital Fund Trust Certificates is categorized as a Level 3 input.
	Investment in Mortgage-Backed Securities. The fair value of the Company's investment in mortgage-backed securities is based upon prices obtained from a third party pricing service, which are indicative of market activity. The valuation methodology of the Company's third party pricing service incorporates commonly used market pricing methods, incorporates trading activity observed in the market place, and other data inputs. The methodology also considers the underlying characteristics of each security, which are also observable inputs, including: coupon; maturity date; loan age; reset date; collateral type; geography; and prepayment speeds. Management analyzes pricing data received from the third party pricing service by comparing it to valuation information obtained from at least one other third party pricing service and ensuring they are within a tolerable range of difference which the Company estimates as 7.5%. Management also looks at observations of trading activity observed in the market place when available. Given these facts, the fair value measurements of the Company's investment in mortgage-backed securities is categorized as Level 2 input.
	Taxable bonds. The fair values of the Company’s investments in taxable bonds have each been based on a discounted cash flow or yield to maturity analysis. There is no active trading market for the taxable bonds and price quotes are not available. The estimates of the fair values of these taxable bonds, whether estimated by the Company or based on external sources, are based largely on unobservable inputs the General Partner believes would be used by market participants. Additionally, the calculation methodology used by the external sources and the Company encompasses the use of judgment in its application. To validate changes in the fair value of the Company's investments in taxable bonds between reporting periods, management looks at the key inputs such as changes in the current market yields on similar bonds as well as changes in the operating performance of the underlying property serving as collateral for each bond. We validate that the changes in the estimated fair value of the taxable bonds move with the changes in these monitored factors. Given these facts the fair value measurement of the Company’s investment in taxable bonds is categorized as a Level 3 input.
	Interest rate derivatives.  The effect of the Company's interest rate caps is to set a cap, or upper limit, on the base rate of interest paid on the Company's variable rate debt equal to the notional amount of the derivative agreement.  The effect of the Company's interest rate swap is to change a variable rate debt obligation to a fixed rate for that portion of the debt equal to the notional amount of the derivative agreement.  The interest rate derivatives are recorded at fair value with changes in fair value included in current period earnings within interest expense.  The fair value of the interest rate derivatives is based on a model whose inputs are not observable and therefore are categorized as a Level 3 input.
	Assets measured at fair value on a recurring basis are summarized below:

	Commitments and Contingencies
	The Company, from time to time, may be subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are frequently covered by insurance. If it has been determined that a loss is probable to occur, the estimated amount of the loss is accrued in the consolidated financial statements. While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material effect on the Company’s consolidated financial statements.
	Certain of the MF Properties own apartment properties that generated LIHTCs for the previous partners in these partnerships.  In connection with the acquisition of partnership interests in these partnerships by subsidiaries of the Company, the Company has agreed to reimburse the prior partners for any liabilities they incur due to recapture of these tax credits to the extent the recapture liability is due to the operation of the properties in a manner inconsistent with the laws and regulations relating to such tax credits after the date of acquisition. No amount has been accrued for this contingent liability because management believes that the likelihood of any payments being required there under is remote.
	The Company provided a guarantee on the $2.8 million mortgage obtained on the Abbington at Stones River, a 96 unit multifamily property located in Tennessee in addition to providing an approximately $1.6 million taxable property loan to Foundation for Affordable Housing, the not-for-profit owner of the property. Based on the historical financial performance of the property and its estimated fair value, the Company estimates there is no value to record for this mortgage guarantee.
	In connection with the sale of the Greens Property, the Company entered into guarantee agreements with the BC Partners under which the Company has guaranteed certain obligations of the general partner of the Greens of Pine Glen limited partnership, including an obligation to repurchase the interests of the BC Partners if certain “repurchase events” occur. A repurchase event is defined as any one of a number of events mainly focused on the completion of the property rehabilitation, property rent stabilization, the delivery of LIHTCs, tax credit recapture and foreclosure. No amount has been accrued for this contingent liability because the likelihood of a repurchase event is remote. The maximum exposure to the Company at December 31, 2013, under the guarantee provision of the repurchase clause is approximately $1.3 million which represents 75% of the equity contributed by BC Partners to date.
	In connection with the Ohio Properties transaction in 2011, the Company entered into guarantee agreements with the BC Partners under which the Company has guaranteed certain obligations of the general partner of these limited partnerships, including an obligation to repurchase the interests of the BC Partners if certain “repurchase events” occur. A repurchase event is defined as any one of a number of events mainly focused on the completion of the property rehabilitation, property rent stabilization, the delivery of LIHTCs, tax credit recapture and foreclosure. Even if a repurchase event should occur, 25% of the BC equity would remain in the Ohio Properties and thus BC, a third party, would have sufficient equity in the Ohio Properties for the Company to recognize the sale discussed in Note 9. No amount has been accrued for this contingent liability because the likelihood of a repurchase event is remote. The maximum exposure to the Company at December 31, 2013, under the guarantee provision of the repurchase clause is approximately $4.9 million which represents 75% of the equity contributed by BC Partners.
	In March 2013, a wholly-owned subsidiary of the Company executed a 35-year ground lease with the University of Nebraska - Lincoln (“Lessor”) with an annual lease payment of $100. The leased property will have a mixed-use development consisting of a 1605 stall parking garage and 475 bed student housing mixed-use project constructed on it. The Lessor will own the parking garage and the Company will own the student housing. The Company currently estimates the construction of The 50/50 Student Housing at UNL mixed-use project will cost approximately $34.0 million and executed a guaranteed maximum price contract with the general contractor for the construction. The lease agreement has a stipulation that if the parking garage is not completed by August 1, 2014, the Company will pay damages of $6,000 per day of delayed completion to the Lessor. The Company's construction contract with the general contractor also stipulates that the general contractor will pay the Company $6,000 per day of liquidated damages for each day subsequent to August 1, 2014 that the parking garage is not completed. Construction has commenced and is estimated to be completed before the August 1, 2014 deadline.
	To finance the construction of The 50/50 Student Housing at UNL mixed-use project, the Company has executed an interest-only loan to borrow up to $25.5 million for a three year term at a variable interest rate. The Company also secured $4.3 million tax-incremental financing loan which is for a term of five years, carries a fixed interest rate of approximately 4.7% per annum, requires principal payments commencing after 24 months and has a balloon payment due at maturity. The Company has borrowed approximately $7.2 million on the first facility as of December 31, 2013 (Notes 7 and 11).
	In June 2013, the Partnership executed a Bond Purchase Commitment agreeing to purchase an $8.0 million new mortgage revenue bond and a $500,000 taxable bond both secured by a multifamily property under construction in Albuquerque, New Mexico. The mortgage revenue bond will have a stated annual interest rate of 6.0% per annum, the taxable bond will have a stated rate of 12.0% per annum, and bond proceeds must be used to pay off the third party construction loan. The Partnership accounts for the Bond Purchase Commitment as an available-for-sale security and, as such, records the change in estimated fair value of the Bond Purchase Commitment as an asset or liability with changes in such valuation recorded in other comprehensive income.  As of December 31, 2013, the Partnership has estimated the value of this Bond Purchase Commitment and recorded a liability of approximately $600,000. The Partnership has two other Forward Bond Purchase Commitments (Vantage at Judson and Vantage at Harlingen) which are discussed in footnote 5.
	The Partnership has also executed a Guarantee Agreement with the construction lender for this Albuquerque project. The terms of the Guarantee Agreement requires the Partnership to guarantee that all construction costs are paid when due and pay any remaining outstanding principal and unpaid interest on the construction loan on or before July 1, 2015. Construction is expected to be completed in the first quarter of 2015 when the Partnership anticipates purchasing the mortgage revenue bond and taxable bond. No amounts have been accrued for this Guarantee Agreement as the Partnership expects that the construction loan will be sufficient to pay all costs during the construction period and that the proceeds from the mortgage revenue bond, taxable bond, and third party equity contribution to be sufficient to pay off all outstanding principal and interest on the construction loan on or before July 1, 2015.
	As the holder of residual interests issued in connection with its TEBS and TOB bond financing arrangements, the Partnership is required to guarantee certain losses that can be incurred by the trusts created in connection with these financings. These guarantees may result from a downgrade in the investment rating of mortgage revenue bonds held by the trust or of the senior securities issued by the trust, a ratings downgrade of the liquidity provider for the trust, increases in short term interest rates beyond pre-set maximums, an inability to re-market the senior securities or an inability to obtain liquidity for the trust. In each of these cases, the trust will be collapsed. If the proceeds from the sale of the trust collateral are not sufficient to pay the principal amount of the senior securities with accrued interest and the other expenses of the trusts, the Partnership will be required to fund any such shortfall pursuant to its guarantee.

	Subsequent Events
	In February 2014, the Company redeemed the mortgage revenue bond secured by the Villages at Lost Creek property. The bond was redeemed at approximately $18.7 million and the mortgage revenue bond had a carrying value of approximately $15.9 million at time of redemption. The approximately $2.8 million gain is Tier 2 income with 25% distributable to the General Partner. Approximately $15.7 million of the proceeds were used to pay down outstanding debt as this mortgage revenue bond was leveraged in the Company’s TEBS financing facility.
	In February 2014, the Partnership acquired a senior $7.0 million par value and a subordinate $2.3 million par value mortgage revenue bonds secured by Harden Ranch, an 100 unit multifamily apartment complex in Salinas, California. The senior mortgage revenue bond carries an annual interest rate of 5.75% and matures on March 1, 2031. The subordinate mortgage revenue bond carries an annual interest rate of 5.50% for the first year and 8.0% for the second year and matures on March 1, 2016.
	In February 2014, the Company entered into two interest rate cap agreements with SMBC Capital Markets, Inc. for a notional amount of $70.0 million with an effective start date of March 1, 2014. These agreements effectively limits the interest component of the TOB financing correlated with the SIFMA index to a maximum of 1.0% on $70.0 million of the outstanding borrowings on the MBS TOB financing facilities and the PHC Certificates TOB financing facilities to 1.0% through a three year term ending March 1, 2017. These interest rate cap contracts cost approximately $390,000 and do not qualify for hedge accounting, therefore, changes in the estimated fair value of the interest rate derivatives will be included in earnings.
	In February 2014, the Company acquired a senior $23 million par value mortgage revenue bond secured by Decatur-Angle Apartments, a 302 unit multifamily apartment complex in Fort Worth, Texas. The mortgage revenue bond carries an annual interest rate of 5.75% and matures on January 1, 2054.
	On March 7, 2014, the Company executed a new TOB Trust under its credit facility with DB securitizing the Decatur-Angle mortgage revenue bond borrowing $17.25 million. The facility has a variable interest rate tied to SIFMA and matures in February 2015.

Segment_Reporting

Segment Reporting	12 Months Ended

Segment Reporting [Abstract]	'
Segment Reporting Disclosure [Text Block]	'
	Segments
	The Company consists of five reportable segments, Mortgage Revenue Bond Investments, MF Properties, Public Housing Capital Fund Trusts, MBS Investments, and Consolidated VIEs. In addition to the five reportable segments, the Company also separately reports its consolidation and elimination information because it does not allocate certain items to the segments.
	Mortgage Revenue Bond Investments Segment
	The Mortgage Revenue Bond Investments segment consists of the Company's portfolio of federally mortgage revenue bonds which have been issued to provide construction and/or permanent financing of multifamily residential apartments.  Such mortgage revenue bonds are held as long-term investments.  As of December 31, 2013, the Company held forty mortgage revenue bonds not associated with Consolidated VIEs and two mortgage revenue bonds associated with Consolidated VIEs which are bonds that are eliminated in consolidation on the Company's financial statements. The multifamily apartment properties financed by the 42 mortgage revenue bonds contain a total of 5,409 rental units. Three of the bonds' properties are not operational and are under construction (Note 5).
	MF Properties Segment
	The MF Properties segment consists of indirect equity interests in multifamily apartment properties which are not currently financed by mortgage revenue bonds held by the Partnership but which the Partnership eventually intends to finance by such bonds through a restructuring.  In connection with any such restructuring, the Partnership will be required to dispose of any equity interest held in such MF Properties.  With the exception of the Ohio Properties and the Greens Property, the Partnership's interests in its current MF Properties are not currently classified as Assets Held for Sale because the Partnership is not actively marketing them for sale, there is no definitive purchase agreement in existence that, under current guidance, can be recognized as a sale of real estate assets and, therefore, no sale is expected in the next twelve months.  As discussed above, the Ohio Properties and the Greens Property are reported as discontinued operations (Note 10). During the time the Partnership holds an interest in an MF Property, any net rental income generated by the MF Properties in excess of debt service will be available for distribution to the Partnership in accordance with its interest in the MF Property.  Any such cash distribution will contribute to the Partnership's CAD.  As of December 31, 2013, the Company consolidated the results of eight MF Properties containing a total of 1,582 rental units plus the The 50/50 Student Housing at UNL in Lincoln, Nebraska that is currently under construction (Note 8).
	Other Investments
	The Partnership Agreement authorizes the Company to make investments in investments other than mortgage revenue bonds provided that these other investments are rated in one of the four highest rating categories by a national securities rating agency and do not constitute more than 25% of the Company's assets at the time of acquisition as required under the Agreement of Limited Partnership. In addition, the amount of other investments are limited based on the conditions to the exemption from registration under the Investment Company Act of 1940 that is relied upon for the Partnership. The Company currently has other investments, PHC Certificates and MBS which are reported as two separate segments.
	The PHC Trusts segment consists of the assets, liabilities, and related income and expenses of the PHC Trusts. The Partnership consolidates the PHC Trusts due to it's ownership of the LIFERS issued by the three PHC Trusts, which hold custodial receipts evidencing loans made to a number of local public housing authorities. Principal and interest on these loans are payable by the respective public housing authorities out of annual appropriations to be made to the public housing authorities by the HUD under HUD's Capital Fund Program established under the Capital Fund Program. This investment has been reported as part of the Partnership balance sheet and results of operations since acquired in July 2012.
	The MBS segment consists of the assets, liabilities, and related income and expenses of the MBS TOB Trusts that the Company consolidated due to its ownership of the LIFERs issued by the MBS TOB Trusts. These MBS TOB Trusts are securitizations of state-issued mortgage-backed securities which are backed by residential mortgage loans. These investments were acquired during the fourth quarter of 2012 through the second quarter of 2013 (Note 7).
	Consolidated VIE segment
	The Consolidated VIE segment consists of multifamily apartment properties which are financed with mortgage revenue bonds held by the Partnership, the assets, liabilities and operating results of which are consolidated with those of the Partnership.  The mortgage revenue bonds on these Consolidated VIE properties are eliminated from the Company's financial statements as a result of such consolidation, however, such bonds are held as long-term investments by the Partnership which continues to be entitled to receive principal and interest payments on such bonds.  The Company does not actually own an equity position in the Consolidated VIEs or their underlying properties.  As of December 31, 2013, the Company consolidated two VIE multifamily apartment properties containing a total of 410 rental units (Note 4).
	Management closely monitors and evaluates the financial reporting associated with and the operations of the Consolidated VIEs and the MF Properties and performs such evaluation separately from the other operations of the Partnership through interaction with the affiliated property management company which manages the multifamily apartment properties held by the Consolidated VIEs and the MF Properties.
	Management's goals with respect to the properties constituting the Company's Consolidated VIE and MF Properties reportable segments is to generate increasing amounts of net rental income from these properties that will allow them to (i) make all payments of base interest, and possibly pay contingent interest, on the properties included in the Mortgage Revenue Bond Investments segment and the Consolidated VIE segment, and (ii) distribute net rental income to the Partnership from the MF Properties segment until such properties can be refinanced with additional mortgage revenue bonds meeting the Partnership's investment criteria.  In order to achieve these goals, management of these multifamily apartment properties is focused on: (i) maintaining high economic occupancy and increasing rental rates through effective leasing, reduced turnover rates and providing quality maintenance and services to maximize resident satisfaction; (ii) managing operating expenses and achieving cost reductions through operating efficiencies and economies of scale generally inherent in the management of a portfolio of multiple properties; and (iii) emphasizing regular programs of repairs, maintenance and property improvements to enhance the competitive advantage and value of its properties in their respective market areas.

Business Combinations Policy [Policy Text Block]	'
	Acquisition Accounting
	Pursuant to the guidance on acquisition accounting, the Company allocates the total acquisition cost of a property acquired to the land, building, and leases in existence as of the date of acquisition based on their relative fair values.  The building is valued as if vacant. The estimated valuation of in-place leases is calculated by applying a risk-adjusted discount rate to the projected cash flow deficit at each property during an assumed lease-up period for these properties. This allocated cost is amortized over the average remaining term of the leases and is included in the statement of operations under depreciation and amortization expense.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Restricted Cash
	Restricted cash, which is legally restricted to use, is comprised of resident security deposits, required maintenance reserves, escrowed funds, restricted compensating balances, and property rehabilitation.  At December 31, 2013, certain of our credit facilities require restricted cash balances as additional collateral. Specifically, the mortgage revenue bond securitization ("TEBS") financing facility, discussed below, required approximately $727,000, the three tender option bonds ("TOB") trusts ("TOB Trusts") secured by the Public Housing Capital Fund Trust Certificates ("PHC Certificates") financing facilities (“PHC TOB Trusts”) required approximately $400,000, and the TOB Trusts secured by mortgage backed securities ("MBS") financing facilities ("MBS TOB Trusts") required approximately $4.1 million held in restricted cash. There were two of the mortgage payables which required approximately $2.9 million held as restricted cash
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash and Cash Equivalents
	Cash and cash equivalents include highly liquid securities and investments in federally tax-exempt securities with maturities of three months or less when purchased.
Consolidation, Policy [Policy Text Block]	'
	Principles of Consolidation
	The “Company” refers to the Partnership and the consolidated VIEs (defined below). The consolidated financial statements of the Company reported in this Form 10-K include the financial position and results of operations of the Partnership, the MF Properties owned by various limited partnerships in which one of the Partnership's wholly-owned subsidiaries (each a “Holding Company”) holds a 99% limited partner interest, two entities in which the Partnership does not hold an ownership interest but which own multifamily apartment properties financed with mortgage revenue bonds held by the Partnership and which are treated as variable interest entities ("VIEs") of which the Partnership has been determined to be the primary beneficiary (the “Consolidated VIEs”). The Consolidated Subsidiaries of the Partnership consist of:
	•	ATAX TEBS I, LLC, a special purpose entity owned and controlled by the Partnership, created to hold mortgage revenue bonds in order to facilitate the Tax Exempt Bond Securitization (“TEBS”) Financing with Freddie Mac (Note 10).
	•	Nine multifamily apartments ("MF Properties") which are either wholly or majority owned by subsidiaries of the Partnership.
	Under the consolidation guidance, the Partnership must make an evaluation of the entities which own the multifamily properties financed with mortgage revenue bonds it holds to determine if these entities meet the definition of a VIE. Generally, a VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support; (b) as a group, the holders of the equity investment at risk lack (i) the ability to make decisions about an entity's activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests and substantially all of the entity's activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights.
	The guidance requires the Partnership to perform an analysis to determine whether its variable interests give it a controlling financial interest in a VIE. This analysis identifies the primary beneficiary, the entity that must consolidate the VIE, as the entity that has (1) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.  Upon adoption of this revised accounting standard, the Partnership re-evaluated all of its investments to determine if the property owners are VIEs and, if so, whether the Partnership is the primary beneficiary of the VIE. The guidance also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. As a result, changes to the Consolidated VIEs may occur in the future based on changes in circumstances. The accounting guidance on consolidations is complex and requires significant analysis and judgment.
	Stand-alone financial information of the Partnership reported in this Form 10-K includes only the financial position and results of operation of the Partnership and the MF Properties without the consolidation of the VIEs.  In the Company's consolidated financial statements, all transactions and accounts between the Partnership, the MF Properties and the VIEs have been eliminated in consolidation.
	The General Partner does not believe that the consolidation of the VIEs for reporting under generally accepted accounting principles in the United States of America (“GAAP”) impacts the Partnership's tax status, amounts reported to Beneficial Unit Certificate (“BUC”) holders on IRS Form K-1, the Partnership's ability to distribute income to unitholders which it believes to be tax-exempt, the current level of quarterly distributions or the tax-exempt status of the underlying mortgage revenue bonds.
Investment, Policy [Policy Text Block]	'
	Investment in Public Housing Capital Fund Trusts Certificates and Mortgage-Backed Securities
	The Company accounts for its investments in PHC Certificates and MBS under the guidance for accounting for certain investments in debt and equity securities. The guidance requires investments in securities to be classified as one of the following: 1) held-to-maturity, 2) available-for-sale, or 3) trading securities. All of the Company's PHC Certificates and MBS investments are classified as available-for-sale, and are reported at estimated fair value with the net unrealized gains or losses reflected in other comprehensive income. Unrealized gains and losses do not affect the cash flow of the bonds, distributions to unitholders, or the characterization of the interest income of the financial obligation of the underlying collateral.
	There is no active trading market for the bonds and price quotes for the bonds are not available and the estimates of the fair values of the PHC Certificates are based on a yield to maturity analysis which begins with the current market yield rate for a “AAA” rated tax-free municipal bond for a term consistent with the weighted-average life of each of the Public Housing Capital Fund trusts adjusted largely for unobservable inputs the General Partner believes would be used by market participants. Management’s valuation encompasses judgment in its application and pricing as determined by pricing services, when available, is compared to Management's estimates.
	The Company periodically reviews each class of PHC Certificates for impairment. The Company evaluates whether a decline in the fair value of a PHC Certificate below its amortized cost is other-than temporary based on a number of factors including:
	•	The duration and severity of the decline in fair value,
	•	The Company's intent to hold and the likelihood of it being required to sell the security before its value recovers,
	•	Downgrade in the security's rating by S&P,
	•	Volatility of the fair value of the security.
	The Company values each MBS security based upon prices obtained from a third party pricing service, which are indicative of market activity. The valuation methodology of the Company's third party pricing service incorporates commonly used market pricing methods, incorporates trading activity observed in the market place, and other data inputs. The methodology also considers the underlying characteristics of each security, which are also observable inputs, including: coupon; maturity date; loan age; reset date; collateral type; geography; and prepayment speeds. Management analyzes pricing data received from the third party pricing service by comparing it to valuation information obtained from at least one other third party pricing service and ensuring they are within a tolerable range of difference which the Company estimates as 7.5%. Management also looks at observations of trading activity in the market place when available.
	The Company periodically reviews each MBS security for impairment. The Company evaluates whether a decline in the fair value of a security below its amortized cost is other-than-temporary based on a number of factors including the duration and severity of the decline in fair value and the Company's intend and ability to hold the security until its value recovers. Each MBS security has been rated either "AAA" or "AA" by either S&P or Moody's. A downgrade in rating for each MBS or new issuances of similar MBS with ratings by S&P or Moody's below the "A" rating would be a factor in concluding that an impairment is other-than-temporary.
	Investment in Mortgage Revenue Bonds and Other Mortgage Revenue Bonds
	The Company accounts for its investments in mortgage revenue bonds and other mortgage revenue bonds under the guidance for accounting for certain investments in debt and equity securities. The guidance requires investments in securities to be classified as one of the following: 1) held-to-maturity, 2) available-for-sale, or 3) trading securities. All of the Company's investments in mortgage revenue bonds and other mortgage revenue bonds are classified as available-for-sale, and are reported at estimated fair value with the net unrealized gains or losses reflected in other comprehensive income. Unrealized gains and losses do not affect the cash flow of the bonds, distributions to unitholders, or the characterization of the interest income of the financial obligation of the underlying collateral.
	There is no active trading market for the bonds and price quotes for the bonds are not available.  As a result, the Company bases its estimate of fair value of the mortgage revenue bonds using discounted cash flow or yield to maturity analyses performed by management. This calculation methodology encompasses a significant amount of management judgment in its application.  If available, management may also consider price quotes on similar bonds or other information from external sources, such as pricing services or broker quotes.  Pricing services, broker quotes and management's analyses provide indicative pricing only.
	The Company periodically reviews each of its mortgage revenue bonds for impairment.  The Company evaluates whether unrealized losses are considered to be other-than-temporary based on a number of factors including:
	•	The duration and severity of the decline in fair value,
	•	The Company's intent to hold and the likelihood of it being required to sell the security before its value recovers,
	•	Adverse conditions specifically related to the security, its collateral, or both,
	•	Volatility of the fair value of the security,
	•	The likelihood of the borrower being able to make payments,
	•	Failure of the issuer to make scheduled interest or principal payments, and
	•	Recoveries or additional declines in fair value after the balance sheet date.
	While the Company evaluates all available information, it focuses specifically on whether it has the intent to sell the securities prior to the time that their value recovers or until maturity, whether it is likely that the Company will be required to sell the securities before a recovery in value and whether the Company expects to recover the securities' entire amortized cost basis.  The ability to recover the securities' entire amortized cost basis is based on the likelihood of the issuer being able to make required principal and interest payments on the security.  The primary source of repayment of the amortized cost is the cash flows produced by the property which serve as the collateral for the bonds.  The Company utilizes a discounted cash flow model for the underlying property that serves as collateral on the bond and compares the results of the model to the amortized cost basis of the bond.  These models reflect the cash flows expected to be generated by the underlying properties over a ten year period, including an assumed property sale at the end of year ten, discounted using the effective interest rate on the bonds in accordance with the accounting guidance on other-than-temporary impairment of debt securities.  The inputs to these models require management to make assumptions, the most significant of which include:
	•	Revenue and expense projections for the property operations, which result in the estimated net operating income generated over the ten year holding period assumed in the model.  Base year (model year one) assumptions are based on historical financial results and operating budget information.  Base year assumptions are then adjusted for expected changes in occupancy, rental rates and expenses, and
	•	The capitalization rate utilized to estimate the sales proceeds from an assumed property sale in year ten of the model.  The capitalization rate used in the current year models ranged between 6.25% and 7.25% which the Company believes represents a reasonable range given the current market for multifamily properties.
	The revenue, expense and resulting net operating income projections which are the basis for the discounted cash flow model are based on judgment.  Operating results from a multifamily residential property depend on the rental and occupancy rates of the property and the level of operating expenses.  Occupancy rates and rents are directly affected by the supply of and demand for apartments in the market areas in which a property is located.  This, in turn, is affected by several factors such as local or national economic conditions, the amount of new apartment construction and interest rates on single-family mortgage loans.  In addition, factors such as government regulation, inflation, real estate and other taxes, labor problems and natural disasters can affect the economic operations of a property.
	If the discounted cash flows from a property are less than the amortized cost of the bond, the Company believes that there is a strong indication that the cash flows from the property will not support the payment of the required principal and interest on the bond and, accordingly, the bonds are considered other-than-temporarily impaired.  If an other-than-temporary impairment exists, the amortized cost basis of the mortgage revenue bond is written down to its estimated fair value.  The amount of the write-down representing a credit loss is accounted for as a realized loss on the statement of operations.  The amount of the write-down representing a non-credit loss is recorded to other comprehensive income. The difference between the amortized cost basis and the discounted cash flows using the effective interest rate represents the credit loss. Any residual decline in value would be considered the interest related loss or non-credit loss. The recognition of an other-than-temporary impairment and the potential impairment analysis are subject to a considerable degree of judgment, the results of which when applied under different conditions or assumptions could have a material impact on the financial statements. If the Company experiences deterioration in the values of its investment portfolio, the Company may incur impairments to its investment portfolio which could negatively impact the Company's financial condition, cash flows, and reported earnings.
	The Company owns some mortgage revenue bonds which were purchased at a discount or premium. The discount or premium on an investment is amortized on an effective yield method and the result is realized in investment income in the current period.
	The Company eliminates the mortgage revenue bonds and the associated interest income and interest receivable when it consolidates the underlying real estate collateral in accordance with implementation of the consolidation guidance for variable interest entities.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates in Preparation of Consolidated Financial Statements
	The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates and assumptions include those used in determining investment valuation, investment impairments, impairment of property assets, and allowance for loan losses.
Derivatives, Policy [Policy Text Block]	'
	Derivative Instruments and Hedging Activities
	The Company accounts for its derivative and hedging activities in accordance with the guidance on Derivatives and Hedging. The guidance on Derivatives and Hedging requires the recognition of all derivative instruments as assets or liabilities in the Company's consolidated balance sheets and measurement of these instruments at fair value. The accounting treatment is dependent upon whether or not a derivative instrument is designated as a hedge and, if so, the type of hedge.  The Company's interest rate derivative agreements do not have a specific hedge designation under the guidance on derivatives and hedging, and therefore changes in fair value are recognized in the consolidated statements of operations as interest expense.  The Company is exposed to loss should a counterparty to its derivative instruments default.  The Company does not anticipate non-performance by any counterparty.  The fair value of the interest rate derivative agreements is determined based upon current price quotes by recognized dealers.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition on Investments in Mortgage Revenue Bonds
	The interest income received by the Partnership from its mortgage revenue bonds is dependent upon the net cash flow of the underlying properties. Base interest income on fully performing mortgage revenue bonds is recognized as it is earned. Base interest income on mortgage revenue bonds not fully performing is recognized as it is received. Past due base interest on mortgage revenue bonds, which are or were previously not fully performing, is recognized as it is received. The Partnership reinstates the accrual of base interest once the mortgage revenue bond's ability to perform is adequately demonstrated. Contingent interest income, which is only received by the Partnership if the property financed by a mortgage revenue bond that contains a contingent interest provision generates excess available cash flow as set forth in each bond, is recognized when realized or realizable. Past due contingent interest on mortgage revenue bonds, which are or were previously not fully performing, is recognized when realized or realizable. As of December 31, 2013 and 2012, the Company's mortgage revenue bonds were fully performing as to their base interest with the exception of the Woodland Park bond in 2012.
	An evaluation was performed during fiscal 2011 which determined that the interest receivable accrued on the Woodland Park bond was impaired and an approximate $953,000 allowance for loss on receivables was recorded. The Partnership received two interest payments during 2012 and recorded an additional allowance of approximately $453,000 against the remaining interest receivable in 2012. The Partnership recorded an approximate additional $242,000 against the interest receivable before the mortgage revenue bond foreclosure was completed in May 2013 and title to the Woodland Park property was conveyed to a wholly-owned subsidiary of the Partnership (Note 8).
	Revenue Recognition on Investments in Real Estate, MBS, and PHC Certificates
	The Partnership's Consolidated VIEs and the MF Properties (Note 8) are lessors of multifamily rental units under leases with terms of one year or less. Rental revenue is recognized, net of rental concessions, on a straight-line method over the related lease term.
	Interest income on the MBS and PHC Certificates is recognized as it is earned (Notes 6 and 7).
Income Tax, Policy [Policy Text Block]	'
	Income Taxes
	No provision has been made for income taxes because the unitholders are required to report their share of the Partnership's taxable income for federal and state income tax purposes.  Certain of the Consolidated VIEs and wholly-owned subsidiaries of the Partnership are corporations that are subject to federal and state income taxes.  At December 31, 2013 and 2012, the Company evaluated whether it was more likely than not that any deferred tax assets would be realized.  The Company has recorded a full valuation allowance of approximately $7.4 million and $10.0 million at December 31, 2013 and 2012, respectively, against the deferred tax assets created at these entities by timing differences because the realization of these future benefits is not more likely than not.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	'
	Variable Interest Entities (“VIEs”)
	When the Partnership invests in a mortgage revenue bond which is collateralized by a multifamily property, the Partnership will evaluate the entity which owns the property financed by the mortgage revenue bond to determine if it is a VIE as defined by the guidance on consolidations. The guidance on consolidations is a complex standard that requires significant analysis and judgment. If it is determined that the entity is a VIE, the Partnership will then evaluate if it is the primary beneficiary of such VIE, by determining whether the Partnership will absorb the majority of the VIE's expected losses, receive a majority of the VIE's residual returns, or both. If the Partnership determines itself to be the primary beneficiary of the VIE, then the assets, liabilities and financial results of the related multifamily property will be consolidated in the Partnership's financial statements. As a result of such consolidation, the debt financing provided by the Partnership to such consolidated VIE will be eliminated as part of the consolidation process. However, the Partnership will continue to receive interest and principal payments on such debt and these payments will retain their characterization as either mortgage revenue bond or taxable interest for income tax reporting purposes. Since the Partnership has no legal ownership of the VIEs, creditors of the VIEs have no recourse to the Partnership.
	Accounting for Tax Exempt Bond Securitization ("TEBS") and Tender Option Bond ("TOB") Financing Arrangements
	The Company has evaluated the accounting guidance in regard to the TEBS and TOB Financing arrangements (Note 11) and has determined that the securitization transactions do not meet the accounting criteria for a sale or transfer of financial assets and will, therefore, be accounted for as a secured financing transactions. More specifically, the guidance on transfers and servicing sets forth the conditions that must be met to de-recognize a transferred financial asset. This guidance provides, in part, that the transferor has surrendered control over transferred assets if and only if the transferor does not maintain effective control over the transferred assets through any of the following:
	1	An agreement that both entitles and obligates the transferor to repurchase or redeem them before their maturity,
	2	The ability to unilaterally cause the holder to return specific assets, other than through a cleanup call, or
	3	An agreement that permits the transferee to require the transferor to repurchase the transferred financial assets at a price that is so favorable to the transferee that it is probable that the transferee will require the transferor to repurchase them.
	The TEBS financing agreements contain certain provisions that allow the Company to (1) cause the return of certain individual bonds under defined circumstances, (2) cause the return of all of the bonds by electing an Optional Series Pool Release or (3) cause the return of any defaulted bonds. The Optional Series Pool Release is defined in the agreements as two specific dates, September 15, 2017, or September 15, 2020, on which the Company has the option to repurchase all of the securitized bonds. Given these terms, the Company has concluded that the condition in item 2 above is present in the agreements and, therefore, effective control over the transferred assets has not occurred. As effective control has not been transferred, the transaction does not meet the conditions to de-recognize the assets resulting in the TEBS financing being presented on the Company's consolidated financial statements as a secured financing. The TOB Financing agreements contain certain provisions that allow the Company to call the bonds held in the tender option bond trusts ("TOB Trusts") through their ownership of the residual participating interests ("LIFERS") so effective control has not been transferred resulting in the TOB Financings being presented on the Company's consolidated financial statements as secured financings.
	In addition to evaluating the TEBS financing as a sale or transfer of financial assets, we have evaluated the securitization trust associated with the TEBS financing facility (the “TEBS Trust”) under the provisions of consolidation guidance. As part of the TEBS Financing, certain bond assets of the Partnership were securitized into the TEBS Trust with Freddie Mac. The TEBS Trust then issued Class A and B TEBS Certificates. Other Company investments are securitized into TOB Trusts with Deutsche Bank AG (“DB”). The TOB trustee then issued senior floating-rate participating interests ("SPEARS") and LIFERS. The Partnership has determined that the TEBS Trust is a VIE and the Class B Certificates owned by the Partnership create a variable interest in the TEBS Trust. It was also determined that the TOB Trusts are VIEs and the LIFERS owned by the Company create a variable interest entity in the TOB Trusts.
	In determining the primary beneficiary of the TEBS Trust and TOB Trusts, the Partnership considered the activities of each of the VIEs which most significantly impact the VIE's economic performance, who has the power to control such activities, the risks which the entity was designed to create, the variability associated with those risks and the interests which absorb such variability. The Partnership has retained the right, pursuant to the TEBS financing agreements, to either substitute or reacquire some or all of the securitized bonds at various future dates and under various circumstances. As a result, the Partnership determined it had retained a controlling financial interest in the TEBS Trust because such actions effectively provide the Partnership with the ability to control decisions pertaining to the VIE's management of interest rate and credit risk. While in the TEBS Trust, the bond assets may only be used to settle obligations of the trust and the liabilities of the trust do not provide the Class A certificate holders with recourse to the general credit of the Partnership.
	The Partnership also determined it was the primary beneficiary of the TOB Trusts as it has the right to cause each TOB trust to sell the securitized asset in each specific TOB Trust. If the securitized assets were sold, the extent to which the VIE will be exposed to gains or losses from changes in the fair market value of the securitized assets would result from decisions made by the Partnership.
	It was determined that the Partnership met both of the primary beneficiary criteria and was the most closely associated with the VIE and, therefore, was determined to be the primary beneficiary under these financing arrangements. Given these accounting determinations, the TEBS financing facility and the associated TEBS Trust are presented as a secured financing within the consolidated financial statements. The TOB Financings and associated TOB trusts are also presented as a secured financing within the consolidated financial statements.

Concentration Risk, Credit Risk, Policy [Policy Text Block]	'
	Concentration of Credit Risk
	The Company maintains the majority of its unrestricted cash balances at two financial institutions.  The balances insured by the Federal Deposit Insurance Corporation is equal to $250,000 at each institution.  At various times the cash balances exceeded the $250,000 limit.  The Company is also exposed to risk on its short-term investments in the event of non-performance by counterparties.  The Company does not anticipate any non-performance.  This risk is minimized significantly by the Company's portfolio being restricted to investment grade securities.
Receivables, Policy [Policy Text Block]	'
	Property Loans
	In addition to the mortgage revenue bonds held by the Company, taxable property loans have been made to the owners of some of the properties which secure the bonds.  The repayment of these taxable property loans is dependent largely on the value of the property or its cash flows which collateralize the loans.  The Company periodically evaluates these loans for potential losses by estimating the fair value of the property which collateralize the loans and comparing the fair value to the outstanding mortgage revenue bonds plus any taxable property loans.  The Company utilizes the discounted cash flow model discussed above except that in estimating a property fair value we evaluate a number of different discounted cash flow ("DCF") models that contain varying assumptions.  The various models may assume multiple revenue and expense scenarios, various capitalization rates, and multiple discount rates.  The Company may also consider other information such as independent appraisals in estimating a property fair value.
	If the estimated fair value of the property after deducting the amortized cost basis of the senior mortgage revenue bond exceeds the principal balance of the taxable property loan then no potential loss is indicated and no allowance for loan loss is recorded.  If a potential loss is indicated, an allowance for loan loss is recorded against the outstanding loan amount and a loss is realized.  The determination of the need for an allowance for loan loss is subject to considerable judgment. For the years ended December 31, 2013 and 2011, the Company recognized a provision for loan losses of approximately $168,000 and $4.2 million, respectively. For the year ended December 31, 2012, the Company did not recognize any provision for loan losses.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Investments in Real Estate
	The Company's investments in real estate are carried at cost less accumulated depreciation. Depreciation of real estate is based on the estimated useful life of the related asset, generally 19-40 years on multifamily residential apartment buildings and five to 15 years on capital improvements and is calculated using the straight-line method. Maintenance and repairs are charged to expense as incurred, while improvements, renovations, and replacements are capitalized.
	Management reviews each property for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of a property may not be recoverable. The review of recoverability is based upon comparing the net book value of each real estate property to the sum of its estimated undiscounted future cash flows. If impairment exists due to the inability to recover the carrying value of a property, an impairment loss is recorded to the extent that the carrying value of the property exceeds its estimated fair value.
Deferred Charges, Policy [Policy Text Block]	'
	Deferred Financing Costs
	Debt financing costs are capitalized and amortized on the effective interest method over the stated maturity of the related debt financing agreement. Bond issuance costs are capitalized and amortized on the effective interest method over the stated maturity of the related mortgage revenue bonds.  As of December 31, 2013 and 2012, debt financing costs and bond issuance costs of $5.3 million and $4.6 million, respectively, were included in other assets. These costs are reduced on the balance sheet by the accumulated amortization of approximately $2.8 million and $1.8 million as of December 31, 2013 and 2012, respectively.
